Hey
zmzmI would recommend you to go through the mistakes from your previous tests and
try to understand where do you make the maximum mistakes. Work on improving
your basics and the
GMATClub Quantitative Mega-Thread is an excellent resource
in order to improve your grasp on the concepts.
Once you have a better understanding of these topics you must solve problems
in these topics. In order to find high-quality questions here on the forum, you
can visit these topics
1. PS Directory by Topic and Difficulty2. DS Directory by Topic and DifficultyWhenever you practice questions, try to understand if you are able to apply the
learning to the problems. Every time you are not able to solve a question go to
the thread(where the question has been discussed) and go through the various
methods that have been used to solve the problems. In my experience, you will
come across a few methods that will help you save some time. Try and adapt
these methods while you solve questions during practice. The idea is to save time
in topics that you are good at so as to give more time to topics where you are still
not up to the mark.
Work on maintaining an
error log and go through the mistakes you make from
time to time. This retrospection will definitely help you improve your scores.
Hope this helps you.
