the answer to your query lies in the the preparation of your +1 itself..
see if u have prepared the portion of +1 upto your satisfaction.. then there is no need to worry about.. just by writing formulae and important concepts for a particular topic .. thats enough..........
for exmaple.,.......
suppose that u are covering the topic of say newtons laws.. then in that case while going across the theory.. u shud write the important concepts and formulae on a seperate sheet... then also dont forget to mention that this step was done in order to obtain this step by doing so and so operation... as a matter of fact.. in 12th when u will come across the across the derivations of finding the magnetic field due to straight conductor ... or a ring .. then in all the cases. u have to take under consideration the line element .. then put the values of sin or cos.. or may be in some cases tan... adn then intergrate..
so try ot write such thumbrules...
then comes the question of revision ..so for that.. the best thing is taking test .. mock tests.. there are many available on the internet freely....... so in this way ..it will help u to revise...
and sorry for writing such a long answer .....cud not help writing
