What are some free online finance resources I can take up to learn more about personal finance and investing? What are some paid courses you've tried and are worth paying for?

In my opinion, most of the information you need is already online. It just needs a bit of digging. Most courses just rehash what is online and I don't feel that it is money well spent. Perhaps if you're looking into investing, you might consider Index Investing to start out as it is quite a passive strategy with minimal finance knowledge required.

With regard to personal finance, without too much knowledge on your current situation, it is a bit hard to give much advice.​​​
