Suggestion: in a round of review, read the book carefully and be familiar with the formulas of vector, triangle, sequence and probability. Senior three did more special topics last semester and sorted out valuable problems (personally, everything that is not necessarily wrong is valuable). You can do more sets of questions next semester to practice speed and accuracy. Some good questions can be done several times every once in a while, and further strengthening the method may lead to some unexpected gains. You must ask questions when you study mathematics in senior three.
This is all my experience. I hope it helps you.
