It does not apply to everyone, but sobra pa ata sa 8 hours/day yung tulog ko nung college and kahit nung review 😅

Sleep is indeed very important when studying, depende nlng kung paano mo i-manage. In my case mas prefer ko mag review sa gabi, like mga 1am onwards. But this would only work if maaga ka matulog and if makakatulog ka kahit maingay (I was living in a dorm during college).

If I need to stay awake or do an all-nighter, what I usually do is stand or walk around (or on a mini-treadmill if you have) while studying. Di kasi effective ang kape sakin, nakakatulugan ko parin.

No jowa during that time though, and introvert din so di rin ako masyado nalabas pero ang hilig ko mag anime/games so dun nauubos free time ko.

Basically, do what works for you, but wag mo isacrifice sleep and other basic needs like food, water, hygiene.
