CA for mains, one can rely completely on Dipin sir's CA classes. I also thought that I will do vision also or Epic magazine but believe me that's is practically impossible. Though Dipin sir gives class notes, one can make short notes of sir's classes for last minute revision.
Another benefit is that the effort that sir puts in will prompt you to work harder.
Another good thing is that after going through the classes, you will gain enough weapons ( read content) that will help you in the war (mains examination).
If one can religiously do the basic books/notes and add that with sir's CA classes, you can aim to be in the top percentiles as far as GS scores are concerned.
PS: When I say religiously, make sure you revise these notes 2-3 times.
Hope this helps.
