SFM RAHUL VA MK

I struggled to Finish Google Drive Classes of SFM of Sanjay Saraf. I used my friends log-in. Even though exam was in 2 months. I didn't watch class. 
I have to retake SFM as my concepts are not strong 
What do the people with Past experience suggest. Live or GD. Someone plz suggest. 

1) Mayank Kothari - 200 Hours - Google Drive 

2) Rahul Malkan - Live Class
