What do u think about sushant padha?

He got AIR-52 from PW n claims he started major prep in half class 11 and then class 12 but only some concepts were done by him in class 10 as of interest but didn't join any coaching and self prep at home with PW online.... Everyone says AIR 100 start prep frkm class 6 or 7, is he an exception? If he could, then can we?
