Senior year schedule?

I’m currently a junior and picking out AP classes for senior year. I didn’t pick out any for this year, but since I’m homeschooled I’m able to do some classes over the summer and since I have some credits I need to do I’m going to add 2 AP classes to the list. I’m also going to be taking a third AP class when fall comes along with my other classes I’ve chosen for senior year. I was wondering how hard each class is.
AP classes I’m taking:
English Lang and Comp
US History
Biology

I was also wondering if the rest of my classes will be enough

My senior schedule:
Pre cal
English 4
Spanish 2
Honors Physics
AP Biology

I don’t have a history class listed since after the summer I’ll be done with my history credits.
