GMAT in 15 days - helpless in Quant

Think on these lines to figure out why you need to guess on last 7 questions:
Do you read and re-read every Quant question before you are able to fully understand what is given and what is asked? If yes, then concentration is your problem.
Do you follow a long winded approach to every question? Do you often find that the solution gives an easier/logical approach? If yes, then it is a conceptual problem.
Do you get lost in a tough question and lose 5-6 mins before you guess/solve and move on? If yes, then time management is your problem.
Do you stop and stare at the question trying to figure out how to solve it before you start solving it? If yes, then practice is the key.

Depending on the problem you are facing, we can suggest a solution.

Its gotta be the 2nd and 3rd points...long winded approach and losing 5-6 mins in a question and then still having to guess and not getting it right..

GMAT does not test your Math skills; it tests your logic. We know that we don't need to do long calculations, make equations and solve them simultaneously etc in our day-to-day work. What we need to do is given certain data, deduce things of interest out of it, use our reasoning skills to infer from the data etc. GMAT does just that - test your reasoning skills. Obviously it needs a framework to test reasoning skills and that framework is provided by Math and English. So what the Quant questions expect from you is not exceptional Math abilities but strong reasoning ability. Most GMAT questions can be solved orally in a few secs. Even the hard ones can be solved orally though you might have to put an extra minute to figure out the logic. So you know that if you understand the topics conceptually, you don't need to use a lot of Math to solve GMAT questions. Look for alternative approaches. I understand that the switch might be hard to make in 10-15 days. Nevertheless, if you use conceptual solutions, you will save a ton of time.

Also, do not give more than 3 mins to any question. If you are unable to solve it in that time, chances are you will not be able to solve it in another 1 min. Even if you are able to solve it given another minute, it will still not be worth it because you will not be able to solve another question since you would have used up its time. The reason I say 3 mins and not 2 is that there will be some questions you will be able to answer in a few secs so you will have some extra time leftover. Not many people would say this but know when to quit on a question. Read this: https://www.gmatclub.com/forum/veritas-prep-resource-links-no-longer-available-399979.html#/2010/10 ... for-field/

I found the GmatClub tests very helpful. After completing them, I was able to quickly approach most questions without wasting too much time. I also felt gutted the first time I took the gmat. I wish I used the Gmatclub tests earlier. They cover everything.

Thanks a lot for the tip karishma...will try to implement it in the next test i take..Do u think maybe revising all the concepts once more may help since they'll be on my fingertrips and will help boost my confidence??....Also for practice..what additional materials should I use?

Thanks a lot for that..Will get on the tests once i'm done with OG quant and verbal

Sure but don't just read through the concepts. You really need to understand them. Check out the posts on our blog to understand what I mean by that: https://www.gmatclub.com/forum/veritas-prep-resource-links-no-longer-available-399979.html#/
Ron often tackles Quant concepts in 'Ron Point', Brian often takes up strategies in 'GMAT Tip of the Week' and I discuss difficult concepts in 'Quarter Wit Quarter Wisdom'.

Also, there is a plethora of practice material at your disposal e.g. our course books provide a ton of questions, we have topic based assignments for you online and we have 15 practice tests (5 of them are brand new and give you a very good idea about the score you can expect in the current GMAT pattern).
