It depends on how much you know about finance. It would be better if you had learned this knowledge before. Just buy teaching materials and supporting counseling books, and nothing else is needed. If you don't feel safe, find one or two sets of real questions online. As for the simulation questions related to the internet, it is completely unnecessary. Just finish the questions in the supporting counseling books. That's what I did. I got 83.5 points in the basic exam in March.
If you know nothing about finance, then one month is not enough. Although these two courses are easy to test, they are memorable compared with those with financial foundation, but they should also be based on your understanding of those concepts, such as futures, options, swaps, depositary receipts and so on.
Good luck!
