Hi Shruti,
Take a study material and start studying chapter wise, solve problems on that topic and take 2 tests after every chapter. You have to analyze your 1st test that where you did the mistake and work on it and then take 2nd test with full preparation so that you'll finish that topic right away. Note- Make notes of all important formulas and points somewhere so that at the exam time you can make a quick recap. Or you can get the formula files online also. If you are already done with chapter wise study then you just need to take tests and brush up the topics in which you are finding difficulties and try to buy a book by Arun Sharma. Arun Sharma book of CAT is best for quant and logical reasoning. All the best.
