Title pretty much explains my question. If I am a stem focused student, which of the two should I take?
If you’ve finished precalc, take M2.
Yes, Math 2.
Math 2 is for students who finish precalculus in 11th grade or earlier.
Math 1 is for students who are unable to finish precalculus in time for the subject test.
Good point above - the Math 2 recommendations assume you are ready to take it, having completed Pre-Calc. If you’re going to take Pre-Calc as a Senior then you would need to take Math 1, typically at the end of Junior year.
