Physics maths tutor is great for short but consice notes. Also for econ textbooks are really good. I would highly recomend buying the cgp economics book.
Theres loads on youtube. An especially good one is perhaps econplusdal. He makes really informative videos. I usually find videos more helpful but in terms of econ im finding textbooks great
Struggling a bit in understanding econ. Can anyone recommend any good websites/ resources?
Websites: Tutor2u, Investopedia, economicsonline (These have some videos / diagrams as well as great explanations that you should be able to understand)
Videos: Econplusdal on YouTube, as someone else has already mentioned, is good.
