Don't try to remember more formulas it will not only create confusion but also takes a lot of Your precise time, Remember most basic formulas and try to learn How to derive others  since most of  the problems will not be formula based but if you are able to derive them then only You will be able to solve Problems. Now, most basic formulas You will remember when You do a lot of Problem-solving otherwise Formulas are useless if you are not able to solve problems. Focus on problems and How to derive formulas not on remembering them.
