Can you give me a few easy study structures

Schedule, start early, take clear notes, things that make you feel comfortable when studying.

Use Cornell Notes

Explanation:

Organize everything by dividing you paper into 4 sections, essential question, notes, test questions, and summary.

Essential Question(EQ) - your point of confusion (poc)

Notes - important information about your subject

Test Questions - question you think that might be on a CBA, Unit, or STARR test.

Summary - define your notes in a more simple short term, and answer your EQ

I hope that this helped you. It's also a study method that a lot of people use in college. So, it might help you understand your POC more and help you study for any subject in school.
