Hello, I don't know if you have been exposed to the above courses, or not at all. If there is, you can study advanced mathematics first, then linear algebra, probability theory and discrete mathematics. Because advanced mathematics is the foundation behind, we should make up our minds and perseverance to study these subjects. If you have studied it before, it will be easier and you can arrange it for one month. However, if you haven't touched it, you will follow this order, but it will take a long time. It will be more effective to study according to 1 book 1 month, consolidate and review back and forth, and arrange the time reasonably. I'm not sure about your situation. I don't know. You can call me again.
