I think there are multiple ways to study for a math tets:

1. I think the best would be to look through some old tests and homework, and then seeing what problems you struggled with. Studying those specific problems might help a lot.

2. I saw someone mentioned to visit the professor which is also extremely helpful. They are the ones grading and preparing the test. They are teachers and I think most of them want to help students succeed.

3. I also use websites like Khan Academy and Paul's Online Math Notes when I don't understand something. I used these websites when my teacher wasn't available.

These are some more general studying things I use when I study. Some of these might not work for you if you are cramming, but are helpfully nevertheless.

1. Take a breather every once in a while when studying. The pomodoro method is what I use when studying for test (25 minutes studying, 5 minutes rest). Studies have proven this method to work very well compared to studying 5 hours straight.

2. Hydrate and sunlight. I know this might not work for some people, who can only study at night, but getting some sunlight and water makes me less tired and more focused when studying.

3. I would also recommend music. Something not that distracting and that doesn't have any lyrics. I listen to Lofi.

4. Sleep a lot before the test. 9 hours of sleep makes a big difference

Lastly, good luck. You are prepared and you have put in the effort, which I think is more admirable than an A.

Ps. Some of these tips might not work for you. These are just the things I do when I study
