Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

I realised your problem.Same thing happens for everyone.But one and only way to memorise the formulae is practice,practice and more practice. Thik do you need any trick to remember the formula (a+b)2 or (a-b)2? No,because you have used the formula for do many times. One thing I can say that proof the formula from the basic whenever you realise that you are not able to remember those. It will help to remember the formulae by the application of it.
