I have trying hard to increase my quantitative score from 40-42 to like 48-50 range. Can someone please shed some light as to what is the right formula to hit that sweet spot of 50? FYI, I have been getting around 15-17 questions wrong in both the Gmat Prep and PowerPrep tests.
I would suggest the following to you:
--> Solve the last 3rd of OG 11
. No point wasting your time of the first 3rd since your score is already around 42. In my opinion, the first 2/3rds of the book will hardly contribute in moving your score up. Most importantly, as many have mentioned, focus on the concepts. Mark all the questions you get wrong and revisit them in 3-4 weeks time. See if you can solve them then.
--> Start solving the questions on the Math forum
here. Though a lot of them are quite hard, they will really push your bar higher. The folks out here are the best and they will really help you understand something that makes no sense to you.
--> As soon as you feel a little confident about taking the next step, gain access to the GMATClub Challenges
. Again, these are a bunch of hard questions and they will surely help you.
Keep this in mind:
--> The more comfortable you get with harder questions, the better (since its adaptive)
--> Unless you keep an error log
(copy and paste the questions that you got wrong into a word doc.) and revisit it periodically, your improvement will be snail paced.
Thanks guys for all the great advise. So far, I have kept
. I have also trying to solve all the questions I got wrong in Gmat Prep and PowerPrep. I have recently bought all MGMAT Quant. books and going over the concepts. These books are really helpful and I can already see some difference in my approach to quant. questions!! I will start solving more problems at Gmatclub.
