Hello

The best and the smart way to remember formulae for long time is to write it atleast 10 times and revise every now and then as much possible. Make keyword type notes and stick in front of your study table where you face and can revise anytime. Also make a separate notebook for it. It'll help you till the end for quick and easy revision.
As and when you practice MCQs .. try to revise the formulae and the solve... This way you'll get an idea of the formulae applications + the logic where and when to be applied..  > by this you will no longer need to remember anything.. because the concept will be clear in your mind.. as you'll solve the maximum number of MCQs ..!
Hope you're getting my point .!
So prepare well and study smart.!

All the Bestt.!!!
