Physics Optional for UPSC 2019
@Alok_Chauhan I'll be starting to solve PYQs in few days after completing the theory part. Would be great for Mains 2019 if some sort of discussion platform is created. May be we can create a telegram group for this. Drop me a text on 9989037913 if you are interested or let me know if some platform already exists.
serious physics aspirant can join this group
@invisible27 thanks a lot
Please update further tests
