Holy seeds of purity

Maybe the rabbi will agree to give a tip on how to study seeds and holy things? I studied as usual, studying and familiarizing myself with the Women's Day of Damages, and I also studied the laws of Shabbat Nida Eruvin and more, and now I want to study holy things. I study it alone and studied Zevahim Gaf"t and I feel like I'm not studying effectively. The topics are scattered and I don't get to everything, I lack knowledge that suddenly becomes apparent in the Mishniyot, I don't know exactly how to define the feeling of sourness. I thought maybe it would be worth studying Mishniyot with Tiferet Yisrael, but sometimes later I feel like I'm fixated on the interpretation in the conclusion of the Gemara with him and it stops my thoughts. It's also difficult because it's not just familiarity, but more than that, but you don't really understand either. Maybe Rambam. Does the rabbi have any advice on how to do it? Does he think studying the tractates that are on the Seder is a good way?
