HOW TO CRACK CA FINAL GROUP 1 IN 3 MONTHS

Hello friends,

please guide me and provide me some tips to crack CA final in 3 months. I had given my attempt in May 18 but failed except in case of SFM 58. I have not cleared any other subjects of group in this exam but want to improve and give my best in Nov 18.
Basically I find practical subjects a bit interesting as compared to theory. so my strategy for the theory subject such as audit and law does not works and whenever I have passed in the previous CA exams I have scored only between 40-47.
So please guide me how to deal with theory properly.
