“I’m taking algebra 2 right now and I have an A, and I got all As in my other math classes.”
Did you have geometry before algebra 2?
If so, then it sounds like you are doing well and it comes down to what you want to do.
In my experience students who are very strong in all of the prerequisites to calculus find it to be relatively straightforward, but students who are weak on the prerequisites frequently find calculus to be tough. I am just thinking that you would only want to take precalculus as a freshman in high school if you are pretty close to certain that you can get an A (or an A+) in it.
