Gmat SC useful Strategy

by jrshaktimaan » Sat Sep 25, 2021 9:24 pm
To ace Sentence Correction you need to have good understanding of english and know grammar rules,vocabulary etc. Yet, this is not enough. You also need to understand what GMAT wants to test using SC.

=> SC is not about correcting few wrongly used words or structures. It has nothing to do with spoken english. It is not similar to TOEFL-GRE questions.

=> GMAT wants to see whether you are to the point communicators,who can understand complex sentences that you will face during your MBA education or in the business world post mba.

=> So your aim should be to understand and find the best way of writing complex sentences(short or long). Almost all SC questions will sound as if they were taken straight from business,scientific journals,papers. Only solve this kind of representative questions,dont waste time on unrepresentative qs. e.g Maria and me are .... This is a simple example but hope you understand what I mean, avoid these questions and any SC material using these questions. You wont see these on GMAT SC.

OVERALL APPROACH

1. Identify What is Asked: Every one of you will solve 100s maybe 1000s of SC questions. Yet most of you will still struggle with SC questions on the exam. Why? Two reasons,you will either just solve questions and wont learn anything or you will learn from the questions you solved but you wont remember to apply what you learned because you wont know what to remember!!!!!!

Forget about the things you read about SC in debriefings. EXCEPT FOR FEW,ALL SC CAN STILL BE SOLVED USING RULES. YES,THERE ARE SOME NEW RULES,TRICKS BUT GMATPREP SHOWS ALL OF THEM,I WILL EXPLAIN HOW TO LOOK FOR THEM.

Whenever you solve a SC question. First look at it and identify what is being tested. Is it testing usage of "both .. and.. "? is it testing usage of present perfect? Or usage of -............- ? Or "a comparison "? Or " meaning" ? Or " WORD ORDER"??

Why identifying what is asked is important?? ==>Because once you understand what is being asked, your brain might retrieve the information you have on this issue. EVEN IF YOU SOLVE 10000 qs,if you dont identify what is being asked, each question will be a completely new question!

2. Identify the parts

This step is optional. So you can directly go to step 3 in general. Yet, if the question is really tough and complex you can in your mind identify the parts of the sentence. Nothing fancy.. Just understand what is doing what. Check the OG question about "fungus extending...". If you realize the question is trying to trick you with lots of words etc. STOP UNDERSTAND THE PARTS,WHO IS DOING WHAT AND HOW. Check that question once again, first just do it straight away,then on the second time, take your time and understand who is doing what and ask yourself can this thing do this action???

3. What do I know?

Now,once you know what is being tested. Just ask yourself: What do I know about ...present tense usage, either ...or..., word order ....

This step is crucial,after taking the real test I can assure you(sorry for being honest) most of the people who say that SC has nothing to do with Gmatprep and that questions are just based on meaning etc are not 100% right. Rules are still there,they are less obvious. BUT THESE RULES ARE LIKE TRICKS IN QUANT,IF YOU DONT KNOW IT IS THERE, THERE IS NOT WAY YOU CAN USE THEM TO ANSWER THE QUESTION.

So after spotting the rules, just ask think for 1-2sc and retrieve all the info you know about everything being tested.

4. Eliminate or not? POE.
Everybody says that POE is very useful when solving SCs. I say it can be very useful but it all depends on 2 factors. You should take these into account before using POE.
a) Length of Question
b) Confidence Level
a) Length of Question
Short Question: The new GMAT style has some very perplexing short SC questions. One example is “As former board member….” Question from Gmatprep. These questions are like the tricky DS questions in quant. It is imperative that you understand not only the meaning but also the trick in the meaning!!!. For example in that question, trick was that the person was not “former” when he/she did the things mentioned in the sentence so no need to use former, “As” would be enough.
When faced with such a question, just stop, remember this tip and look for the trick in the meaning. Don’t use POE and try to apply some rules to eliminate choices or don’t use POE and your ear!!! (please note that it is always good to eliminate the answer choices you think are wrong, what I mean here by “don’t use POE” is: don’t compare choices and try to understand which one is better etc.”) In these questions, once you see the trick etc. you will be able to directly click and confirm.
Long Question: Most of SC question will be 2-3 lines and rather complex (if you are scoring above 40). As haddy once said, “it is not easy to read 5 long choices very similar to each other and pick the right one without getting lost”. Add to this the claim that all SC now are based on meaning and that one has to read all choices fully and understand the meanings then answer … This explains why so many people, already tired from the quant section, can not cope with these beasts.
What I do: I use POE to the max. WHY? Because although I agree that you have to read the whole sentence (not underlined part as well) before answering a SC, I don’t think you have to understand the meaning fully etc. We are not solving RCs, you wont get questions on the SC sentence you just read. SO, just having a general idea about the meaning of the sentence is enough. Take for example the OG question where GMAT talks about some Islamic groups in the past and list them and says “ …manifestation of…..” . The answer to the question is correct because it uses comma correctly and links items listed with and etc. When solving that question and similar ones,you just need to understand what is going on: Question talks about some groups and says that their ….is ….. That is it. Unless you feel there is a trick( in the form of word order,I will talk about this later), just go directly to the differences among choices. How???? Just check the rules 1 and 3,4 above. Ask yourself what that question testing: Lists? Use of “and” and “comma” (of course it tests other stuff too but these are the critical ones). Then ask yourself what you know about the notions tested. Then use POE. Don’t bother with meaning etc.
I solved some long SC questions very quickly not because I am a genius but because I mastered this technique and applied it with confidence. That brings us to my next point.
Confidence Level: I know some of you think, if nothing works in SC I can look at answer choices and use POE or some others think I will use POE in all SC questions. I don’t wanna shatter your dreams BUT YOU WILL EITHER NOT ABLE TO USE POE OR BE HURT BY TRYING TO USE IT, IF YOU ARE NOT SUPER CONFIDENT.
So it is crucial that you develop extreme self confidence in SC (again low self confidence will hurt you most in SC and not in RC or CR).This is what will happen if you don’t have self confidence and try to use POE,
-You will read choices 2-3 times, you will read choices that you know are wrong for sure. You will doubt your logic for eliminating a choice; you will decide to reread the sentence given. Clock will still be ticking….
- None of the choices will look correct. They will all seem to have a minor mistake in different part of the sentence. You will think, damn the real SC is really difficult,it is not like GMATPREP’s.
I know these because this is exactly what happened to me in my first attempt. So here is what I did this time:
- I solved almost all questions to apply my technique above. Never have I solved a SC question without following my method. This increased my confidence and made sure I know what to do in the real test.
- Confidence level is a subtle thing to measure. How do you know whether you are confident enough etc? I used to measure my confidence level by checking if I can say this every time I solved a Gmatprep q: Is this the best you can do buddy??. If you read my debrief,you already know that I said this a lot in the real thing and thought I screwed verbal and was getting easy SCs. Let s make this clear,if you are not making fun of GMATPREP SCs, you wont be having fun on the test day when you solve SCs. SCs on the test will be very similar to the ones on GMATPREP but you have to be confident and cool to see this. Otherwise, everything will look tougher.
Confidence level is most important for two types of GMAT question: Sentence correction and Data Sufficiency. Make sure you have a technique, of which you are the master.
5. Reading the whole sentence before confirming:
A bit over-rated (especially for non–natives) step but still you can use it.

Why over rated? Because unless you know what you are looking for reading the same thing for another time wont help you much. You won’t have a AHA! moment unless you know why u are reading it and what you are looking for!

After all the work you do on a tough SC question you might still have 1-2 doubts left in your mind. The purpose of final look at the question as a whole should be to check those 1-2 doubts not just read to repeat the sentence to yourself.

Also, for the last time you should repeat yourself the reason you chose that answer choice
FINE POINTS OF SC: WHAT WILL CHALLENGE YOU?
Tough SCs: Overall, there are so many ways SC can get tough so this list is not really exhaustive. I will add more as I remember.
1)Long SCs
As I explained above, if you start doing well, you will get longer SCs.
To me, if you like to score above 40-42 in verbal, you don’t have the luxury to read all answer choices in these long SCs.
Remember during verbal section, you have to change how your brain thinks: CR,RC are close(yet still different) but after solving them when faced with a SC question: YOU HAVE TO GO BACK TO YOUR SC TACTICS.
What I do: Step A: Read the main sentence very carefully, spot problematic areas and in the other 4 answer choices, first check those problematic areas. If some choices are outrageously wrong, there is no point in reading them again and again
Step B: If I am left with two very close answers, I would read them word by word and compare how they differ. Check first for grammatical problems then for meaning.
As I said above, unless there are two very close answers, these ''tough'' questions are very ''easy''!
2)20% Wrong 80% Correct SCs! : 2 close answers
Now listen folks, this is the biggest trick you will see on SC. I sincerely think this trick is playing with our brains and using our weak human nature to make us choose the wrong answer!
In some SC question, GMAT will give you two very close answers.
One will be 80%-90% correct and will have all the nice grammar rules you learnt, YET it will have a questionable word, usage in the remaining 10-20%. Your brain, hypnotized by halo effect and the familiarity of the usages in the 80% part, will try to disregard this 10-20% wrong part. You will hear yourself saying: Okay, this is it, it has all the things I learnt and I spotted them well, the remaning part is not crucial.
Then there will be another choice, a choice with unfamiliar usages, rarely seen words and very blurry meaning. Your brain will instantly ignore this choice (THIS IS A TRICK USED IN CR TOO!!!). For a native, this situation may never arise,because they may never be very unfamiliar with any usage. But for us, unfamiliarity is a killer. If you are lucky, you will go back to this choice(after reading the above mentioned 80% correct choice) and check it again. You wont be able to find anything wrong yet your brain will look at it negatively.
Well guys, note that this is intentionally done by GMAT so that you choose the choice with familiar usages but one minor flaw over the choice that is not that nice , familiar but without any mistakes.
One example would be two answer choices, one using because the other using due to the fact that ( it is not a 100% representative example and I will exaggerate)
a)US army has left Russia in '79 because food supplies were dwindling.

b)US army left Russia in '79 due to the fact that there were no food supplies left.
Now here, obviously the first choice looks sexier,cleaner YET it has a major flaw, it uses present perfect to talk about a specific event that took place in 79!
Again I exaggerated here and maybe the second answer is not the correct answer you would see on GMAT but still. Hope you see what I mean.
3)Battle of the Bad and Ugly: Wrong choices!!!
All Gmatters will face this moment: What the hell. They are all wrong.
Sometimes GMAT will give you 5 answer choices, neither of which is a clear winner. The bad thing is that you don’t see many of these questions before the test. In general most of the questions posted have somewhat clear answers (except for few).
I must also say that in my test, I didn’t feel facing any of these questions, but, at the risk of sounding snob, I have to say, you may feel this way if you are not very comfortable with SC.
Now, these questions are not really about English not about usages word choices bla bla(although at the end of this post, in the Final Tips section I will give specific ways you can note the difference between answers)
The best thing you can do to prepare for these questions is to
TO SOLVE ALL TERRIBLE QUESTIONS DISCUSSED IN THE FORUM. The questions that will make you go : Oh well, this would not appear on the test , I am sure! Manhattan SCs that will make you cry… SC posted by ''wish4vish'' by myself!
It is true that questions on the test are much more clearer and some of the questions posted in forums are really wrong! Yet solving those questions, or attempting those questions, will help you develop a unique ability: Choosing the best out of the worst.
What I do: 1) I eliminate the worst of worst pretty quickly. If there are 5 very bad choices , I should be confident that I can eliminate the worst 1-2 easily!(if not why I am dreaming about 700+ score anyway!)
2) Then, I always repeat to myself why I think a choice is wrong. When I find that I am thinking it is wrong for not a concrete reason but for an unfamiliar usage, different meaning etc.; I put that answer choice aside. Nonnatives remember you can never beat GMAT if you pretend you are a native and assume you can know all the usages in English etc. IF YOU DON’T HAVE A CONCRETE REASON TO ELIMINATE A CHOICE( GRAMMAR RULES) DON’T RUSH.
3) Then, I weigh the remaining ones using the '' severity of the mistakes'' they include. My simple order is obvious grammar mistakes, subtle grammar mistakes (word order), gmat preferences(because vs. due to the fact that), overall meaning(meaning not related to the previous mistakes, in other words I would spot a meaning mistake caused by word order in an earlier step.)
I repeat if you are not very good at SC and you know this, you are lucky. I am telling you that you will face the Bad-Ugly situation all the time.
Solve all questions which became a hot topic in the forum (there is red envelop on the left of the question title). Solve all Manhattan SCs (though some are not 100% correct IMO,as I said above,this is for practice). Solve all questions posted by Wish4vish and the 30 Questions I posted 1-2 months ago. Read the final tips section of this post(it will be at the end) to better approach these question types and quickly spot the best of the worst.
Whatever you do, don’t say that none of the answer choices makes sense or is correct! The answer is just one click away and is standing right in front of you.

Hello! Here are additional thoughts from us.

GMAT Sentence Correction Tips

1. Learn common GMAT idioms.
A good command of idioms is a great way to eliminate answer choices. In some cases, knowing the correct form of an idiom can get you down to two answer choices.

2. Watch for Parallel Construction Errors
Parallelism is an important way to analyze GMAT sentences. But, you need to be careful about what needs to be paralleled in the sentence.

3. Eliminate Answer Choices
Many examples had answers that obviously repeated the error. So, once you’ve identified an error, take a look at the answer choices to see whether there are any other answers that repeat that same error.

4. Word Order Matters
Some examples played with how the placement of phrases in a sentence affects the meaning of the sentence. In some cases, shifting even one word around can create a disjunction between the intended and grammatical meanings of the sentence.
