When should I start fool proofing?

So I am just now starting logic games and I am somewhat confused on when I should be doing the full proof method. Is that something that should wait until I start to PT, or should I full proof the problem sets from the CC as well? I am completely new to the games, and as expected I struggled on the first sequencing games. I am still having some trouble understanding if I need to go back and do the game over again or not like the full proof method says to do. If so, am I supposed to full proof every single problem set game that I struggle with initially?
