fair enough, I prefer trig ident to combinatorics cuz I dont like it. Proofs is just way too hard for me personallyI don't even do extension but I've done it and whilst being annoyingly hard it doesn't give the same feeling of frustration trig identities give me. Literally when I think I've done everything our head teacher of math pulls questions unseen by humanity out of the blue..... All fun and easy whilst ur practicing until the actual test
