Current affairs - haven't read the monthly magazines

Has anyone joined MK Yadav's INA? Can you please revert back? I had a few questions.

If someone has not read monthly current affairs magazines, would his classes  are of any help? Asking for mains point of view.... specifically for consolidation of scattered information.

I am having trouble in starting answer writing. I feel that I don't have any worthwhile content...Considering the fact of being insincere in my preparation on reading the mains analytical part of current affairs magazines.
