I’m a student in HS, currently taking trig. I was signed up to take honors pre calculus this year, but I had to switch it to trig because taking pre calc would mean that I’d have to drop leadership, and give up the title of junior class Vice President. I feel like taking ap calculus is the necessary class that would help me get into the colleges I’m shooting for (UCLA, UCB possibly but just dreaming). However, I really don’t think that trig has prepared me for it. With this being said, I’ve never received anything less than an A in any high school math class, and I’m an extremely hard worker. I NEED ADVICE. Thoughts? 
What are the math sequence options and prerequisites in your high school?
Usually trigonometry is bundled with precalculus as the course immediately before calculus, but some high schools rearrange the math curriculum to move trigonometry to algebra 2.
Here are some placement tests that you can try to see if you know the prerequisite material to take calculus:

@ucbalumnus Thank you! I’ll look over the placement tests. Students taking trig this year are expected to take either regular calculus or ap stats next year, and most students in honors precalculus are expected to take AP calc AB next year. This is why jumping from trig to Ap calc is a bit of an unusual switch due to the difficulty or gap in material.
