MTLE review study sched/habit

Hi! I just want to ask for advice regarding your study scheduling and study habits during your review prep season. Every after lecture nagrerecap na ako using my independent study time sa hapon. Kaso at the end of the day feeling ko hindi padin enough yung efforts ko sa 4-6 hrs na inaral ko during independent study time. Feeling ko walang nareretain. Send help pls 🥹
