HI anuarumugam13,

Many Test Takers spend 3 months (or more) on their studies before they hit their 'peak' scores, so it's likely that you just have not put in enough time and effort yet.

Before we talk about anything else, can you tell me the name of the 'book' that told you the last 20 questions in each section "didn't matter?" If it wasn't a book (maybe it was on a website or from a user), then can you name the source?

When you took your CATs:
1) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
2) Did you take them at home?
3) Did you take them at the same time of day as your Official GMAT?
4) Did you do anything that you weren't allowed to do on Test Day (skip sections, pause the CAT, eat/drink while taking it, etc.)?

Using this 360 as a gauge, you have some serious work to do to raise your Official Score to a 500+. Thankfully, that goal is reasonable, but you'll likely need far more 'structure' in your studies and the proper guidance to make sure that you're training in the proper way.

GMAT assassins aren't born, they're made,

I know I will get a lot of flack on guessing for last 20, but I honestly thought the last 20 didn't matter. I read in a book that the computer zeroes in on your score after the first 10-20, so I assumed that if I did well on first 20, the last 20 would essentially not matter. Was this wrong? I'm confused about computer adaptive and what it means.

This fact is as far from the truth as it can be or it is a very distorted version of the fact. It would be interesting to know the source.
The CAT keeps on adjusting your score based on the difficulty of the questions that you get correct.

While it is true that the first few questions play a vital role in building your score, if you guess on the rest of the questions, you score will surely go for a toss (and it did)
Each and every question is important on the GMAT.

As OptimusPrepJanielle pointed out, this is incorrect. Take a look at what the OG says about this:

Quote:
M(yth) – The first 10 questions are critical and you should invest the most time on those.
F(act) – All questions count.

It is true that the computer-adaptive testing algorithm uses the first 10 questions to obtain an initial estimate of your ability; however, that is only an initial estimate. As you continue to answer questions, the algorithm self-corrects by computing an updated estimate on the basis of all the questions you have answered, and then administers items that are closely matched to this new estimate of your ability. Your final score is based on all your responses and considers the difficulty of all the questions you answered. Taking additional time on the first 10 questions will not game the system and can hurt your ability to finish the test.

didn't read all the replies but you should also have read that if you don't finish there's a big penalty, I think that happened to me the first time on my quant, not sure if I hit the confirmation on the last one in time but I also did very poorly on the quant, like 30 something percentile.

Also, what it says about the first 10 questions sounds more like if you want to get 100% on the test you need to get those first 10 questions right...

Hi WayneHam,

As long as you bubbled one of the five answer choices on the last question in the section, then you received credit for answering it (even if you didn't hit the 'confirm' button before the clock ran out). Even if you had completely run out of time and not answered that last question, the penalty associated with not answering JUST 1 question is minimal, so that would not be enough to explain your overall Scaled Score/percentile in that section.
