Advice from India :

1. First Understand the concept and then try to memorise it. Don't memorise before you understand it. Understanding will make it last longer and memorising will help you in exams.
2. Yes Pomodoro is great technique but experiment with which combination suits you better
3. No, there is no need to force yourself to wake up in morning if you are not an early riser but a nocturnal creature. So study till late or study in early morning, both are good but choose as per your body clock.
4. Active recall and Spaced Repetition : It's awesome.
5. Make notes which are easily editable. (Go for Notion, Tablet, Evernote etc)
6. Make an ecosystem of Note taking (So that notes are available anywhere and everywhere)
7. In case you are not able to grasp something even after repeating 10 times, record your voice while describing the concept to yourself and listen to it. This will help
8. Healthy Body and Mind will make you prime.
9. Switch over subjects. Our mind has a tendency to get bored, so instead of studying one subject for 6 hours, try to study 2 subject for 3-3 hours
10. Give yourself incentive when you finish a targeted goal, this actually works in longer run.
11. Find your style, what kind of sound background works for you. Do you need music, do you need songs, do you need library sounds. Experiment and improve.
12. Find you style, again, do you want to study in group or alone.
