Dear Aspirant,

If your aim was to just remember the formulas then no techniques will help you as the human mind is tends to forget things in a matter of two weeks. However, there is one technique available and that is also the best technique.

All you have to do is solve some good questions on that formula and you're all.set to go. The more questions you solve, the more formulas you'll remember. Start with NCERT examples and then move to the excercise section. Also you could use some good book like irodov, HC Verma, etc.

Hope this helps. Thank you.
