Sfm theory

Hello Friends, My attempt is may 2015. I have a query regarding theory for Sfm in finals. From where shall I study that? I tried module, Sd bala but both are humongous and seems impossible to learn. Is practice manual enough for theory? I have also heard that aaditya jain sir theory booklet is nice. If anyone has it please send me the soft copy at my id. active.aashi @ gmail.com
