Strategy to achieve good marks in sfm

hello all CCI members .

i am doing self study for SFM with Rajesh Makkar sir's class notes along with J B Gupta sir's book (J B Gupta referred only for some conceptual clarity in special cases) , .

I wanna know what strategy or a game plan should i follow to achieve good marks in SFM .

should i refer any other book too ?

is Makkar sahab's class notes are sufficient ??

thanks in advance

regards
