SFM

Speaking only from a professional point of view regarding the explanations provided on the subject SFM by Mayank sir as per my point of you you shouldn't go for him instead look out for the following teachers provided below and enquire if any Fast Track batch is provided by them:
1. NAGENDRA SHAH SIR
2. SANJAY SARAF SIR

Please note that I am nowhere related to any of these teachers and happened just to take amendment and revision lectures from all of these teachers.

Yes he is good......
