Attend tution .

SST is a subject which most students like to avoid it.The best way is to go through each chapter of your book in details,ie,have a thorough reading of that particular chapter not only once but at least for 2-3 times n underline important points before going through exercises at the end of the chapter.Try to learn Q n A and revise it regularly on daily basis.Then tell me whether you improved your SST or not on my mail id:- imcool_vishwajeet@rediffmail.com

You can go to Libraary, read lot of books, take the help of your freinds or go to tution.
