best prep to go from 600 to 700+

by megabuffo » Tue Jun 02, 2009 2:18 pm
I have 3 months and I'm trying to move from my 600 (actual GMAT) done in a messy 3 weeks prep to a 700+. I'm scoring at 95% in RC, 65% in CR and PS and drastically bad in SC (45%) and DS (50%) and I'm thinking about taking prep lessons, group or private, in some of the most famous stuctures : Kaplan/manhattan..



Anybody can advise the best one for high achievers?
Thanks a lot

Dude,
I am in a similar situation as yours:

out of all the tests taken so far
GMAT Prep 1, GMAT Prep 2, Princeton review, and four tests from 800 score.com - 2 weeks of preparation, I am averaging rather dismal
Quant - 44 (least 39, highest 49, median 45)
Verbal - 34 (least 31, highest 39, median 33)
So If I take a test with this level of preparation I might get somewhere in the 630 - 680 range which is ridiculous.

My weaknesses in quant are:
1) silly mistakes
2) not evaluating all conditions in DS
3) reading the question wrong or incomplete
4) time management

Verbal:
1) RC - 50% hit rate
2) CR - 75% hit rate
3) When I am reading something I tend to get distracted by other thoughts. That is frustrating as I try to read the same stuff again and again wasting valuable time.

Improvements:
- For CR I am going to do some CRs from LSAT preparation. I have read that those CRs are hard and train you for GMAT easily
For silly mistakes in quant, I just need to practice more and more under timed conditions.


I am surprised how your RC hit rate is that high and your SC is low!! Usually its the opposite because SC can be broken down easily and reconstructed using some simple memorized tricks from books like manhattan sc guide, OG, etc. My biggest weakness is RC cos I get distracted so much. CR, i haven't practiced enough.
200 or 800. It don't matter no more.

Kaplan is great for students aiming for 500-650. However, students trying to score higher should consider using a different source of prep, such as Manhattan GMAT.

I took four out of five 800 score.com tests and have wound up my first phase of prep of two straight weeks.
Lowest score was 600 and Highest score was 770. Such a variation is ridiculous, although I made huge strides in sentence completion. I am going to take a break from tests and focus on concepts and finishing up the books now. Dude hows your prep coming up?

My situation is very similar. I to score low in SC(60%) and DS(80%). I am going to buy Manhattan for SC. From what I read from lots of testtakers it is very good source.
For DS, I narrowed down my mistakes to "Properties of numbers"
Thats how it has been listed in OG12.
These are the problems related with prime numbers, SD...etc..

I follow different approach to Q and V. My focus is to get all correct in Q and minimize mistakes in V. I am very good in Math as Engineer so I understand all explanations quickly. Since English is not my first language Grammer is the biggest issue for me. But I do understand my mistakes in review. Manhattan has some nice hints to remember types of SC so I would suggest that.
Best luck!

hey gmatplayer are you using OG12 for practice ? Can you just tell us how different it is from the 11th edition? Any major changes/shifts?:?:

Actually i am in the last leg of my preparation and i m done my prep with OG 11.. I ll be taking the test very soon, within 15 days.. do u think it would be ok if i completely leave out OG12 and go ahead with my existing preparation?

please suggest!

GMAT Score:770

Guys, I'm sorry, but 800score is just no good. Their tests aren't even adaptive, as far as I could tell, since I tried to retake the first one and the same exact questions popped up!

Kaplan is not perfect, but it can't be ignored either. IMHO, it kind of complements the OG guides nicely, since Kaplan also throws in some useful strategy tips. Their problems seem to be more on the academic side and less focused on the word problem aspect of the GMAT. I personally don't share the opinion that Kaplan is just for 650. Some of their problems are actually quite advanced (don't think of calculus, but think of small tricky problems that really test your attention), particularly in the Kaplan 800 book and in their tests. I was slightly disappointed by their verbal, though and this is most obvious in their CR questions, which I believe are not quite GMAT-styled.

Claret, to answer your question: I took my test about a month ago and used the old version of the OG for my prep. I believe it was sufficient, given my score. However, if you truly feel that you need more practice and can buy the OG quickly (i.e. not wait for it to be delivered or smth like that), then go for it...

thanks DanaJ!

Your profile flashes an impeccable 770, so i can safely go by your advice!

As far as practice material is concerned i have plenty of it and have covered the following books

kaplan premier 2008
kaplan 800
princeton crack gmat
OG 11
OG verbal workout
OG math workout
Manhattan SC

I have also taken the following tests in a single sitting with the AWA sections:
APR-MAY
KAPLAN 1 600(31V,41Q)
KAPLAN 2 610(33V,40Q)
KAPLAN 3 590(31V,41Q)
KAPLAN 4 600(31V,41Q)

APR-MAY
PR 1-700(39V,48Q)
PR 2-690(34V,51Q)
PR 3-600(33V,40Q)
PR 4-600(30V,43Q)

MAY - JUN
MGMAT1-710(41V,45Q)
MGMAT2-700(40V,46Q)
MGMAT3-640(33V,45Q)
MGMAT4-680(36V,46Q

GMATPrep 1 : 700(V35, Q49)

Despite taking so many tests, my confidence level is pretty low. Primarily because my first attempt at GMAT was a nightmare. I scored much below my practice tests and even below the GMAT prep test scores.

The blunders that i committed in the first attempt were
1) Not utilizing the breaks : I completely ignored the two breaks thinking that they would hamper my flow. I was completely wrong.

2) Lost out on stamina : By the time i reached the verbal section, i had difficulty maintaining my concentration. I could hardly get my composure back to normal.

I really do not want to take any chances in the second attempt and am targeting at least a 730.
Your tips and suggestions are much required to accomplish this goal of mine!

I am soo scared of the test that i cant even muster enough courage to book the test date. And i also realize that I should not be postponing it further as i might end up losing the much required focus..

So here's a sincere request to all you able , experienced members of the club to guide me through this ordeal. My primary concern is what to do in last 15 days of preparation to hit the bull's eye??? Basically how do i wind up my preps ?


Thanking in anticipation,
Claret


P.S : Since I am a newbie here I am less familiar with the rules of the forum .If I have posted my query in the wrong thread, kindly redirect me..

Ugh... I've seen you post this message ten different times, including once in this thread... Please avoid repeating yourself so much! Of course, you are allowed to write whatever you want, but if you just write the same two phrases without any other comment, it's not going to help anyone... Particularly since you seem to be promoting the MGMAT so much... We are trying to help each other out and produce quality content! All the best!

Claret: There is not accurate way of predicting your scores based on your practice tests. However, many have noted that GMATprep is the closest thing to the real test, so if I had to take a stab at it, I'd say you are around the 700 range. Keep in mind that the test is around 30 points off, meaning that if you get a 700 in the GMAT, your level is somewhere between 670 and 730. Now, while the upper part of this interval does brush with your target score, you can obviously spot a risk here!

About your blunders: the biggest blunder you've made is, IMHO, considering your prep an ordeal. I've written about this before in the "I just Beat the GMAT!" section: https://www.beatthegmat.com/dana-s-tale-t36576.html
Basically what I want to say is that seeing your prep as a chore and hating the test will not yield maximum results. Trust me, all you have to do is just read a RC passage, for example, in a different state of mind (like you actually care about the subject matter instead of just being worried for your score) and you'll see the high quality of its structure and vocabulary. Just try to enjoy yourself with the GMAT! Worrying too much about it isn't going to get you anywhere, except maybe down Nervous Breakdown Lane... Remember: you can always retake!

Now, apart from your mindset (which should obviously be very positive, no matter how bad you did the last time), there isn't much help I can offer, since you haven't told me your weak spots. I'll tell you what I did before the test, though: I read the whole PowerScore CR Bible, one of the best test prep material out there (CR was always my weakness). PowerScore is well known in the testing business for their LSAT prep material, so they did a mighty fine job about the CR section. Their questions were the only ones that were truly GMAT-styled! You'll see what I mean if you compare any question from the Kaplan book to any question from the OG: the OG answers are crystal clear, while there could be some debate about the Kaplan ones...

The best of luck with your prep! And remember: if you don't feel that you're quite ready yet, then postpone it for a while (not too much though... maybe 2 more weeks?). There's no reason in going into battle with a crippling fear of the test! You'll just set the tone for another disappointment, and besides, the admissions "season" is months away...

Hey Claret,
OG12 just more problems I think I read somewhere in this forum the exact comparison between 11 & 12. You can search it. But I don't think you must have it. Doing OG is necessary, 12 is new version with few more problems
BTW I should write too much since I have not seen 11.

Received a PM from claret asking me to respond to questions upthread. Claret, the link you sent me directed me specifically to your post about OG12 vs. OG11. Is that what you wanted me to comment on, or did you want a comment about what to do in the final 15 days? I'll respond about the OG12/11 stuff, but let me know if you wanted to discuss the "final 15 days" issue.

OG12 and OG11 overlap a huge amount. There are only about 300 questions in OG12 that are new / different from OG11. So at this point, I wouldn't worry about it. If you were starting new, I'd say you might as well get OG12, but it's not a big deal at this point.

If you want to read a bit more about the differences between the two, take a look here: https://www.manhattangmat.com/official-guide-12.cfm (Not trying to promote my company - I just don't know any other source for a good analysis of the new book! :))

No problem!

(Also, I find it funny that someone upthread has been recommending our challenge problem archive enough that others have been getting annoyed. I actually tell my students to avoid the archive. :) At least half of the problems are harder than anything you'd see on the test, and the solutions involve calculations that you'd never be expected to perform on the real test.)

This is what I tell my students in general for the final 2 weeks. (I also give them more specific advice based upon what I know of their strengths and weaknesses, but I don't know yours, so you will have to fill in those blanks.)

Two weeks before: take a practice test (not GMATPrep; something that gives you data on timing, difficulty levels, and your performance). Go through that test to determine your current strengths and weaknesses based upon both accuracy and timing. DO NOT pay attention ONLY to accuracy. I review student tests all the time and students will tell me "Oh, I'm not so great at X." I'll look at X and discover that the student spent half the time s/he was supposed to on those because the student had spent way too much time on other questions elsewhere in the section - no wonder "X" wasn't so good!

If you use MGMAT tests, here's the data to look for:
First, from the question lists (listing each question you did in each section). Review:
- problems on which you spent >30 sec above or >45sec below what you were supposed to on problems of that type
- problems below your level that you got wrong - eg, if you're currently scoring 650, look for problems in the 500-600 category
Pat yourself on the back for things on which you scored >50% correct (the higher, the better) and for things you answered correctly in the general timeframe you were supposed to spend. For things you answered correctly very quickly, do still pat yourself on the back, but know that doing something too fast increases the chances you'll make a careless mistake - so just be careful.

Second, from the assessment reports:
- areas on which you scored <50% correct
- areas on which you averaged >20sec above or >30 sec below what you were supposed to average
- areas on which there is >30sec (overall question categories) or >45sec (question subcategories) disparity in timing (in either direction) between the ones of that type that you got right and the ones that you got wrong

** Note on some of the average timing data: if your timing got messed up in the section (eg, you spent too much time early on and had to rush later on), then your data will be skewed because you will have been forced to do questions towards the end much faster than you'd otherwise have done them (possibly to the point of making random guesses in a few seconds). If this happened in either section, you'll have to dive down into the data for individual problems rather than use the assessment reports to do the work for you, because the average timing may seem to be okay even though you had a bunch that were too long and a bunch that were too short.

Now, where are you spending too much time and where are you spending not enough? In which sub-categories are you consistently missing things? Why? (Specifically, why did you get wrong anything that you got wrong?) What could you do / change in order to avoid each specific mistake you made the next time you do a similar problem?

Don't forget to prioritize based upon the frequency with which various things appear on the test. If I got that combinatorics question wrong, and I'm two weeks before the test, I don't care - because combinatorics problems aren't that common and my time is better spent on stuff that is more common. The one thing I'll check to make sure is that I didn't go OVER time in getting that one wrong, because I don't want to lose time on this one (or any question on the test!).

Okay, so you've done all of this analysis. Determine:
(a) what your strengths are - question type, content area, etc.
(b) what your weaknesses are - ditto

For weaknesses that are frequently tested, try to get better at those. For weaknesses that are NOT frequently tested, let them go. Know what they are so you can recognize them when they pop up on the test, know how to make an educated guess, try it, make a guess if necessary, and then move on at or before the expected time limit for that type of question.

One week before:
Before you take your final practice test, develop your Game Plan. Know what your weaknesses are so that you can practice letting them go during your final practice test (as described in previous paragraph). Know what your strengths are so that you can determine when it's worth it to spend a little extra time - eg, you see something that's a total strength for you, but it's also a really hard problem. Here's where you may want to spend an extra 30 seconds (NOT when there's a really hard problem in your area of weakness!).

Take your final practice test about 1 week before (minimum 5 days before the real test). Implement your Game Plan (as described above). When you're done, review your test from the point of view: did I stick to my Game Plan? How did it work? If I didn't stick to it, when and why did I get off track? How did that hurt me?

Do the strengths / weaknesses analysis again and tweak your Game Plan accordingly (for the big day!). Spend the last week doing high-level review:
- major strategies for the different question types
- major strategies for different quant content areas
- educated guessing strategies for different question types / content areas
- timing / pacing strategies (on individual questions and over the entire section)
- major rules / formulas you need to know (NOT every last little thing; just the most frequently-tested, major stuff)

Don't forget: top performance requires you to let stuff go sometimes. That includes this review you're doing in the final few days - if something is just not working for you and that something is not that common anyway, forget about it!

Day before:
Get everything ready to go: ID, food for the next morning, food and drink for the test center, any medication, anything else you want to bring. Also rip out or photocopy the very first page of easy questions from OG from whatever question type is your biggest strength. Know how to get to the test center. Have a back-up alarm clock. Etc.
That evening, go see a movie or do something else that will occupy your attention without tiring you out. Don't spend the night before studying. You either know it or you don't at this point!

Day of:
Get to the test center 30-45 minutes early. Right before you go in, spend 10 minutes doing some of the very easy questions you ripped out of the OG book. Don't check the solutions (don't even bring the solutions with you). What you're doing now is jogging around the track, stretching your muscles, warming up for the big game. Don't try anything crazy and injure yourself (read: don't do hard questions and/or check the solutions on easy questions and risk killing your confidence).
On the breaks (during the test), have something to eat and drink. Stretch. Do jumping jacks or jog in the hallway. Listen to your iPod (if they'll let you - they may not.) Anything to loosen up, get your blood flowing and spike your energy levels.

Good luck!

Thats was great advice Stacy! And good analysis of weakness points.
I will follow that when I take the test. From now what I see it is sometime in August
