Need Guidance for CA FInal

Main ek saal pahele AFM Lecture liye the from Aditya Jain Sir se after completing the lectures muje wo confidence nahi aa raha hain revise karne ja raha hu to kuch concept yaad nahi aa rahe hain.I guess muje lagata hain ki maine wrong faculty choose karli hain jo muje suit nahi hui so how should i coup with this and revise AFM for the may 2026 attempt
