Everything You Need To Know About Time Management (Part 1)

  • Timing

I haven’t picked too ambitious a title there, have I? ;) Let’s see how we do!

Time management is obviously an essential GMAT skill, and one of the (many!) skills we need for this test is the ability to maintain an appropriate time position. “Time position” refers to the relationship between the test taker’s position on the test (the question number) and the time that has elapsed to get to that point in the section. For example, if I’ve just finished quant question #5 and 15 minutes have elapsed so far, am I ahead, behind, or on time?

Check out the table below to help answer that question:

In my previous example, I would be behind on time because, on quant, we’re expected to average about 2 minutes per question. After 5 questions, only 10 minutes should have elapsed – so I am 5 minutes behind, putting me in a negative time position.

Most people will find themselves in the “negative” position more frequently than the “positive” position. If we run out of time before completing the section, we’re going to incur a huge penalty because either we’ll answer a bunch of questions incorrectly in a row (random guessing just to finish on time) or we’ll actually leave questions blank (and that incurs an even higher penalty than the first scenario).

It can also be very problematic to be too far in the “positive” position, though. If you’re answering many or most questions way too quickly, then you’re also likely making a lot of careless mistakes, and that will kill your score by the end of the test.

Ideally, we’d like to remain “neutral” throughout the test, which means that we stay within two to three minutes of the expected time. Sometimes, though, we’re going to get off track. So how do we remain “neutral” as much as possible? And when we do get into a “positive” or “negative” position, how do we get back on track? That’s what we’re going to discuss in this series.

(1) Understand how the scoring works

If you don’t understand how the scoring works, you’re probably going to mess up your timing.

(A) Everyone gets a lot of questions wrong, no matter the scoring level; that’s just how the test works. Pretend you’re playing tennis. You don’t expect to win every point, right? That’d be silly. You just want to win more points than your opponent (the computer)!

(B) Getting an easier question wrong hurts your score more than getting a harder question wrong. In fact, the easier the question, relative to your overall score at that point, the more damage to your score if you get the question wrong. (Note: it is still very possible to get the score you want even if you make mistakes on a few of the easier questions.)

(C) Missing three or four questions in a row hurts your score more, on a per-question basis, than getting the same number of questions wrong but having them interspersed with correct answers. In other words, the effective per-question penalty actually increases as you have more questions wrong in a row. This, of course, is exactly what happens to someone who maintains a negative time position on the test; even if you notice and try to catch up toward the end, you’re likely to end up with a string of wrong answers in a row.

(D) The largest penalty of all is reserved for not finishing the test – another possible consequence of maintaining a negative time position.

(2) Know your per-question time constraints and track your work

When practicing GMAT-format problems, ALWAYS keep track of the time for each question, whether you are doing one problem at a time or a set of problems at once. (Note: “GMAT-format” means questions that are in the same format as one of the official GMAT question types. If you are doing other type of problems – say, math drills – you do not necessarily need to time yourself.)

So what does that all mean? If we want to finish the section on time, then we have to hit the average expected timing. At the same time, averages are only averages – you’re going to have some faster questions and some slower ones.  The “Min and Max” numbers reflect a different consideration. First, I want to make sure that I’m generally spending enough time on questions that I don’t make a bunch of careless mistakes simply due to speed. On the flip side, if I’m spending more than about 30 seconds above the expected average, the chances are very good that the question is just too hard for me (and, if that’s the case, I’ve already spent too much time!).

Keep a time log that reflects the time spent on EVERY problem. (Note: if you’re taking our course, use the OG Archer online program to time yourself and keep track of all of your data.) If you make your own log, it might look like a rough version of this:

On the Data Sufficiency question, the test taker had a negative 10 second position; on the Sentence Correction question, the test taker had a positive 15 second position, and so on. Group the question types together in the log (so, instead of mixing types as the above chart does, keep one log for Data Sufficiency questions, a separate log for Sentence Correction questions, and so on). Highlight questions on which you fell outside of the “Min / Max” time range.

If you use ManhattanGMAT’s OG Archer, note that you’ll have all of the timing data saved for you automatically, but you’ll still have to keep track of which questions fall outside of the “Min / Max” time range. Click on the “Review Your Answers” link to view a list of the problems, and record the too fast and too slow problems in a log of your own.

(3) Reflect On Your Results

The log will make you aware of your pacing on a single-problem level, and will force you to consider the time as you work through a practice problem. Aggregate the data to determine those question types that are generally costing you time (a significantly negative time position overall). If you’re using OG Archer, you can see this aggregate data on the Statistics tab (in Table or Graph format).

Next, note whether you’re getting these “negative position” questions right or wrong (across the various categories – for example, Rate problems or Modifier SCs). For those that you’re answering correctly, the primary question to answer is: how can I become more efficient when answering questions of this type? For those that you’re answering incorrectly, the initial question is simply: how can I get this wrong faster? (I’m getting it wrong anyway – so if I can get it wrong faster, which shouldn’t be that hard to do, then at least I won’t be hurting myself on other questions in the same section.)

How do you get things wrong faster? Well, I’m exaggerating a little bit here, but what I really mean is: do NOT spend extra time on these questions (wrong and slow) no matter what. You may be able to learn how to make a decent educated guess – and you should certainly try! Longer term, you may then decide to study that particular area / topic more closely in order to try to get better.

Also notice those questions that are buying you time (a significantly positive time position overall). First, make sure that you are not making many careless mistakes with these; working quickly is never a positive thing if you sacrifice a question that you were capable of answering correctly. You may actually need to slow down on some of these in order to minimize your careless mistakes.

If you do find areas that are both highly accurate and very efficient, excellent; these are your strengths and you should be very aware of those while taking the test. For instance, if you discover that you’re in a negative time position, you should still take your normal amount of time to answer any “strength” questions; don’t sacrifice the ones you can answer correctly! Instead, make a random guess on the next “weakness” question that you see in order to get yourself back to a neutral position.

Okay, that’s all for today; keep an eye out for part 2 (click here to read part 2), where we’ll discuss “developing your 1 minute sense,” using benchmarks to track your time throughout a test section, and what to do if you find yourself too far ahead or behind during the test.

    Hi Stacey,

    I have started preparing for GMAT exam from past 1 month. so far my preparation is going good however i am facing difficulty in sentence correction and data sufficiency topic. 

    Quite frankly, my english is not very good, i do make lot of grammatical mistakes. I am kind of less confident in this section. Most of the time i find it difficult identify mistake in sentence correction question.

    And for data sufficiency, i have gone through enough material still i find every other question as a new concept for me.

    Can you please suggest me how to improve on these topic. I am counting a lot on your guidance.

      What materials are you using? Have you read this article:

      http://www.manhattangmat.com/blog/index.php/2011/05/16/developing-a-gmat-study-plan/

      It's important to make sure that you find some books or resources that help you learn how to tackle these question types - not just practice problems. What books are you using?

      I would also recommend that you go through my archive of articles here on BTG - I have many, many articles on both SC and quant. Start with these:

      SC: http://www.beatthegmat.com/mba/2010/06/03/how-to-read-a-sentence-correction-problem

      DS: http://www.manhattangmat.com/blog/index.php/2011/05/06/rephrasing-data-sufficiency-questions/

  • Ankur Johar on February 12th, 2012 at 7:17 am

    Hi Stacey,

    I am using Manhattan Sentence Correction guide for SC, PowerScore CR Bible, and Manhattan Books on Inequalities. 

    After reading SC, i got clarity on grammar but still i  find it difficult to identify errors in questions. Though i try to apply concepts on it but sometime i couldn't make what exactly is the problem and same applies to DS questions as well.

    For improving my english i have also started reading New York times.

    Today i gave my first practise exam of GMATPrep and my result is very disheartening. Score 400: quant 15 correct and english 22 correct. though i have been doing stuff from past 1.5 month. It looks like i am working as an adhoc not in right direction. 

    Analysis of test says most of the question on Geometry and Data sufficient are worn in Quant section
    and in Verbal question on sentence correction were wrong.

    Can you suggest me how should i attack my weak area. Do you think i should refer to some other study material??

    Regards,
    Ankur

      Yes, I would recommend our Foundations of Math and Foundations of Verbal books to give you a good solid grounding in the material. After that, you have materials for SC, CR, and algebra, but not for the rest of the topics - you need materials for RC and the other 4 quant topics (number properties, word translations, geometry, and fractions, decimals and percents).

      Next, you should use the article I linked to last time (Developing a study plan) to start setting up a study plan for yourself. You may also decide that you want to take a class. If so, first work through the Foundations of Math and Foundations of Verbal books, because most classes will assume that you have already studied that material.

    Stacey,
    I have heard that even a 770+ test takers get 30%-35% answers wrong because of the adaptive nature of the test. However, I have seen, from GMATPrep, that to score higher, one has to have a high accuracy. For instance, I have scored 720 with 8 incorrect answers in Verbal (ignoring Quant portion). 710 with 9 incorrect answers in Verbal (ignoring Quant portion). 690 with 11 incorrect answers in Verbal (ignoring Quant portion). 

    Any thoughts?

    Thanks
    Winnie

      You'd really need to look at the data for the verbal score alone. Someone scoring 95th+ percentile is going to get far fewer questions wrong than is typical for most test-takers. Though, even at that high a level, we still do get more wrong than you'd normally expect for paper-based tests (where the score is based on percentage correct).

      Also, we're not 100% sure how GMATPrep works with respect to experimental questions. On the real test, somewhere around 10 questions are actually experimental / don't factor into your score, so there could be a big difference in terms of which questions you're missing.

      If GMATPrep counts all of the questions in calculating the score, then the algorithm won't work exactly like the real test algorithm (because more questions are being counted, so each individual question is worth less). If GMATPrep assigns the experimental label to some questions and doesn't count them, then it really matters which are which - and we don't know.

      From research that has been done, I think GMATPrep does actually count all of them - but then that means that we can't draw conclusions from how GMATPrep works and apply exactly to the real test, because they're not using the exact same algorithm.

    In further on the correct/incorrect answers ratio, I have read your other blogs that even the 700+ scores will have 60-40 correct to incorrect answers ratio. I do have the same results in GMATPrep as Winnie; i cannot score above 40 if have more than 8 incorrect, 42 only if i limit to 5-6 incorrect and I can get scores 44-45 if i have only 2-3 incorrects. ( For all these high scores errors were spread out evenly, no continous errors).

    I agree your point that we do not know how GMATPrep counts the experimental quesions, but then my question is - On what basis do you say that in real GMAT 700+ will have 60-40 ratio or 750+ will have 70-30.?? Have any one did research on real GMAT??

      We don't know the exact numbers for sure - they don't release the info. And when I've said that you can score a 700 while still having that ratio, I wasn't discussing the full story. We really shouldn't be talking about the overall 3-digit scores when talking about this - because you can have very different combinations of quant and verbal scores to get a 700.

      You can score a 700 while scoring only, say, 70th percentile in quant but 90-something in verbal (or vice versa). The lower of the two sections will be in that 60-40 range (and that is a range, not an exact number). The 90th+ percentile score, however, is going to be maybe 70% right, maybe 80%, depending on how high that score actually is. (And, at the 99th percentile level, maybe you're getting 90% right - but you're still getting a lot wrong relative to the scoring level, right? Most people would assume that a 99th percentile score would be 100% right... but not necessarily.)

      So you can score a 700 and yet still have a section that is 60-40. Once you get up to 730+, however, both of your sections are likely pretty high percentile-wise (unless maybe you're in the 99th percentile in one sub-section). 750, 760 - same deal, you have to score really well in both, so now maybe you're getting 70%, 80% right - again, it depends on the subscore / percentile ranking for each individual section.

      Make more sense? :)
