If you have any advice, please please please let me know.
I would suggest going through crash course videos, most of them are pretty helpful for a general background of topics.
If you want to go more in depth watch khan academy videos, they are pretty good at teaching concepts.
Good luck on your mocks
Thanks for the advice! I will check Khan Academy out!
Maybe try breaking it down onto posters, flash cards, mindmaps, whatever works best for you.
Just remember, even if you're not happy with your results, right now they're just mocks and it's not the end of the world, you'll have months after that until the real exams to improve
