Have you done numerical ?so first learn formulas

my personal opinion is that when you practice questions it will be quiet useful because it not only helps you to remember the formula but also it helps you to get a clear idea of where the formula should be applied and you can get a clear path…

and also when you read the formulas and go for the question,you might get collapsed at times……..

but after practicing all the sums i advice you to read the formulas first and revise because after practicing certain sums regarding the formulas..they will be fixed into your memory…

but if you think that reading formulas first will be quite useful for you …then go with it..but make sure that you know certain fundamental basics and you must be

good at understanding the theory part well such that you will be able to know where these formulas must be applied and where they should not be..then you will be able to memorize/take these formulas into your heart…
