Official : Post Daily Routine & Self Assessment (Mains 2020)

Hi, need some suggestions for prelims 2020:

I haven't prepared CA well, done 5-6 Vision monthly and now have completed S&T, envy. and Polity 365. Do you think revising 365 will be better or I should do something else.

And in static parts should I revise basic books of polity, mod history, environment( I have read them 2-3 times but not in recent 2-3 months), like I understand basic story/ concepts but make mistakes at facts.

So should I revise notes of Laex rapid reckoner or some other short notes or go by test papers. 

Please suggest, I am losing confidence from 2-3 days that now if I can complete things or not?!!
