Guide to avoiding STUPID mistakes on GMAT [#permalink]

1. Read questions carefully. Dont assume what they are asking for.
2. If x is defined as a number, not an integer, it can assume a range of values, +ive, -ive and fractions. Very easy to miss this and screw up on DS questions.
3. Understand what '0' is - very important.
1. SC - just because you see a choice which sounds reasonably good, don't stop. Always read all the 5 answer choices and pick the best one.
2. RC - don't worry about assessing the difficulty level of a question. I've seen several posts in multiple forums which assert a direct correlation between question difficulty and your performance on the test. While that is likely the case for any CAT, there are several experimental questions on the test and you will never be able to identify them. Also, what is easy for you may be difficult from GMAC's perspective and vice-versa. Getting a long RC passage only if you doing well is a myth - I took the test twice. In the first instance, where my verbal score was dismal, I got some really tough and long RCs (possible cause for my crash-and-burn performance on that test). The second time, I was getting worried since I was getting questions which all seemed fairly easy (not a single long RC). I scored ~25 percentile points more (93rd percentile) on the second test.
3. Make use of the break(s) - every minute of it. They are there for a reason and there are no extra points awarded for getting done early.
4. CR - be wary of questions that use multiple negatives. Always translate to the simpler form before you work the problem. Also, not weaken doesn't necessarily mean strengthen and vice-versa. For example, "Each of the following statements if true, weakens the argument, except" - means which one of the following does not weaken the argument. The correct answer doesnt necessarily have to strengthen the argument - it can be totally irrelevant as long as it doesnt weaken it.
Hi, I am new to gmatclub and this is my first post, so please bear with me if you have already heard some of my questions/ comments posted before.
I found that umashg's comment on reading all the choices (especially for CR on verbal) is very true. (If you think option 3 is right, also read options 4 and 5 just to make sure you eliminate them).
My question - Does anyone think that if you feel strongly about one answer, you should consider not reading any others that follow?
some mistakes I should be careful of... [#permalink]

still 1.5 month for me for the D day....hope this is not too early to figure out my errors...
some tips i found useful...
1. In SC uses of "being", passive voice are not preferred.
2. In DS and PS, 1 is not considered prime number
3. Must practice with timer visible, as must not spend more than 3 mins for PS/DS or Verbal, should assume something and keep going, the pressure keeps on mounting if take too much time on 1 question, I still need to improve a lot here
4. Must include AWA in practice tests, even one is authoriatative in essays , energy usage do count. It is different ball game sitting for 3.45 hours and sitting for 2.35 hours considering 5 mins breaks in between.
When picking numbers, always try to pick easy numbers for the first go around but stay away from 0, and 1 because they can make even wrong statements right. DON'T forget to try negatives, fractions, and zero.
Use 100 when you see a %
Be careful when reading the stem of questions.If you know the type of number your looking for then you half way there to a correct answer.
Non-integer= x/y, where y>x can be either negative or positive
Consecutive= n, n+1, n+2, can be either negative or positive
Positve integer= 1,2,3,.....
Negative integer= .....,-3,-2,-1
Zero is even but neither positive nor negative
Even Prime= 2
Prime= 2,3,5,7.....(there are 25 prime numbers <100)
DON'T forget that moving equations around can help to solve a problem too.
Not all information given in the stems are relevant.
I just thought of one for the DS questions. If the statment is something like is ax=3-bx?, the answer can be no. It took me quite some time to get out of the mind set of trying to figure out which one of the options would make ax=3-bx (as an example)! Basically, you are trying to figure out if (1) or (2) or neither or both can give you a definite answer, whether it be yes or no.

I would like to add: 1. Not taking enough rest before the test day. 2. Taking test in morning - (holds true for some people)
Unfortunately, where I live (applicable to both the city in which I work, and the city where my family lives), I can't get an appointment any later than 10:30. I think I might actually take this while on vacation back home, as the test center is only a short walk, whereas here I'd have to brave the ever unpredictable emerging market traffic.

DS common mistakes that I make ..X is an integer I condsider it x=1/2 ;also when it comes to mean and Standard deviation questions I get so nervous and end up making a mistake. With RC I get impatient while reading a boring passage I need to improve on this a lot ... ....................................................................................................................................... The Price of discipline is always less than the pain of regret.
