GMAT score of 510 in first attempt of GMAT

Hello prathi123,

i understand your pain regarding scores. You have got a very less score but you should not be disheartened about it. You should get motivated and try to get a better score above 700 which is easily available if take the right approach.
Firstly, if you were getting just 510 and 440 in the 2 official test , you should not have taken the exam and rescheduled to get a better score after few months.

As per your statement you have solved OG and read Manhattan strategy guides. So I think you have done much work already and this much preparation is enough to fetch you a score in the range of 720 - 780.

The problem with your preparation according (this is just my assumption) is probably
1. you haven't solved the questions considering the time for each questions. You need to maintain your accuracy within time frame for each question. It is very important to solve each question within time frame. GMATClub has a very good feature of timer and it can be used to solve even OG questions and other questions posted daily to solve and practice within time limit.
2. Why didn't you solved DS questions fully from OG. If you would have solved OG questions, you could have got better score in QA in the range of 48-51.
3. Again you have planned your exam in September may be to catch the deadlines of the B-school. This is really a wrong approach to take exam when you are not fully prepared just to meet the deadline of the application. Ultimately if you don't get a score, you will not apply or will waste money on applications and will not get any call.
4. After the first disastrous score you what should have done.
a. You should have talked to some good friend of yours to get motivation (A friend should be one who knows your full potential).
b. You should have made a list of mistakes which, according to you , is the reason behind your low score, For e.g. QA (Not practiced DS question. Not practiced using timer, Not solved OG problems myself and instead just went through solution), VA: was not able to understand CR and SC concepts.
c. Then you should have started targeting those mistakes for continuous 2 months without any expectation. The present motive of yours should have been to improve ur QA and VA ability and not to a big GMAT score.
d. Next step was to take mock and then make a reality check. If you have improved, there is a potential of improvement. If you have not improved. no point of taking another test just leave the exam and do something else in life. Why to waste time if you can't improve anything in 2 months of dedicated studying. But I am sure you would have improved. Everyone does if he/she has a desire to beat the odds.
e. Now you should have studied for one more month to improve the left weak areas.
f. This was the right time to take another mock. And if you would have got a good score, this was the right time to schedule your test. Schedule a date one month from this date.
g. Now brush up your concepts and solve questions with timer for next 30 days. 20 ques QA (PS and VA) 20 ques VA (CR, SC, RC) daily.
h. Go for test and I m sure you are above 750....

Try this approach and no one will stop you from getting a top score in GMAT..
