Hi!
When you think about the best ways to revise, it is always best to find what works best for you. There are four main types of learners. These types are visual, auditory, reading/writing, and kinaesthetic. I will give you some examples below for each type:
Visual - Make flashcards, posters, turn long notes into concise bullet points.
Auditory - Use mnemonics, listen to a podcast/YouTube video, make up questions and ask someone to test you verbally.
Reading/Writing - Quite self-explanatory but take lots of notes, read through them, turn diagrams and charts into words.
Kinaesthetic - Associate your notes with actions, make your notes into a powerpoint and present them.
Once you have found a method that works for you, I would speak to your teacher about how you can best use that. It's always good to have a few points from key theorists such as Marx, but if you can remember some from lesser known theorists then it shows you have done more extensive reading.
Feel free to ask if you have any more questions!
