frst of all make your understanding clear , by reading the the ncert , while reading the ncert take a marker pen and highlight each and every formula with that , and every morning u need to look upon that formula only , suppose u finished chemical bonding today , then tomorrow morning u need to look up the chem. bonding formula first and then start a new chap .
and while learning the formula , dnt learn it by heart.. question yourself why that formula came and where it came .
that will help u to derive that formula , but no long derivation , only short one . so, that in exam if u forget something u can work it out .
and also be carefull abt the units , thats very very imp. in physics .
and 1 more point while reading formula , just try to remember it by any short woord or mnemonics .
example –
formula for electrical energy – VIT ..
u can remmeber it by remembering vellore institute of technology .
ALL THE BEST
IF U ARE FACING ANY PROB . IN ANY NUMERICAL PROB . POST IT ON THE FORUM ..
