Need good Maths teacher

Any good yt channel for maths that has short videos for revision, but the points are pyq based and video length doesn't go over ~2hrs? I watched physics from eduniti and almost done with it. Did NCERT + Sakshi vora old jee brief for revision, that worked as well. Did Functions from Vora classes old JEE brief, and after matching with my coaching material, there are literally a lot of things he's missed. Would love some teacher who is pyq based and covers things fast. I just need a theory overview, don't need in depth rn for mains. I'll cover the understanding part in solving pyqs.
Thanks 🧡
