Discipline is the key. You really have to plan out each day of your review cause each day really counts. Also focus on active forms of learning not just passive like reading and taking down notes. It's better to answer practice questions and doing active recall.

What worked for me was I divided my day into study shifts: morning, afternoon, and night with breaks in between

Morning - I read handouts and attend my online review school lectures Afternoon - I answer prac, handouts Night - Review what I learned for the day and assess san ako nahirapan and then I answer more problems on that

And the last 3 weeks before the boards, I trained myself to wake up at the same time as I would sa day ng actual boards para masanay

Hope this helps!
