hello nikhitha..,

The best way to learn math quickly is to focus on the things you absolutely need to know and to make sure you have a solid grasp of the most important topic. All you need to do is to solve as many variety of problems as you can. I want to say that daily, minimum you should give 1 to 2 hours for mathematics to improve your mathematics . Understand the concepts behind the problem.  Try yourself without seeing the solution .see the solution only in case of when you are exhausted in methods .

hope it helps..

all the best..
