math placement test(s)

if anyone has any advice (like types of questions, difficulty, which topics to focus on) for the following exams pls drop them below pls:

1. the general math one (lowk dont gaf too much since i got a 5 on BC but dont want to fk it up too badly. also pls tell me i wont need to relearn series)

2. the multivariable test (highkey dont wanna retake multi so pls hook me up with the sauce 🙏)

3. the lin alg test (same as multi, would rather not retake lin alg)

P.S. i havent started reviewing any of ts yet cuz this was a last min decision ngl and its been like 2 years since i last touched lin alg (and 1 yr for multi). thanks!
