Which math class should I take after calculus?

Currently, I am a sophomore in the state of Texas. I have just finished BC Calculus, and expect to get a 5 on the AP test (I got a 5 on the mock exam.)
Next year, I will have access to the full range of university math courses. I will be taking at least 3 more semesters of college math before graduating high school. I plan on majoring in Biochemistry.
What is the best math class to take after Calculus 2? What order should I take my next 3 classes in?

Diff Eq, perhaps? Calc 3?

Does your school offer AP Statistics? If not, would you be interested in self-studying it? It may be good, considering you want to go into Biochemistry, which most likely involves managing data. After that, Calculus 3 is most likely the next best class to take.

Calc 3, Linear Alg, Diff. Alg, Multivariable

brendauo101 lists the three most common post-Calc II courses (Multivariable/Calc III, Linear Algebra, and Differential Equations). At most places, these can be taken in any order, though check with your university-- it might have a suggested order or more prerequisites.

Thanks @pseudoprimal My school has arrows pointing to all three, with no particular recommended order. Are multivariable and calc 3 the same class?

Yes, Calc III and Multivariable are the same.

You can check out MIT’s OCW Scholar Single Variable Calculus and Multivariable calculus classes as a review/preparation. I’d do Multivariable first, then either one of the two, plus Discrete Math at any point.
For Biochem, Biostatistics is a must (NOT AP Stats which is a diluted, easy version of a college stats class that’s unlikely to be very satisfying).
I’m not sure whether you’d be allowed to do that, but I’d do Multivariable, then either [( Linear Algebra and Biostats) + (Diff Eqs and Discrete Math)], or any combination of 2+2.
