I'm in need of a good guide for conjugation. I've tried Tae Kim and some others but they were no help at all. They said the past tense of 行く would be 行かなかった were as all my vocab and phrase studies would have the past tense be 行きました. So it was pretty rough trying to memorize conjugation rules when none of the words in my actual use were following what those were teaching.
So, is there some guide and maybe a practice site/app that can teach me conjugation that has ます、ました、ません、and such, rather than かなかった and all those?
