Tripling up on AP Sciences

Hi, I’ll keep this kind of short, but I’m a junior and I want to be an engineer and I’ve been thinking about my senior year schedule even though its kind of early, but I think it will go something like this:

Normal English
AP Stats
AP Physics 2
Band
AP Chem
AP Comparative Government
Study Hall

I know AP comparative gov seems out of place but It’s the same teacher that I had for AP gov and I think he’s a great teacher. But the question is wether or not I should take AP bio in place of something else. All the Ap sciences have great teachers but I don’t know if I should triple up on sciences. If it helps I got an A in an honors Chem class and a mid B in an honors bio class.
Thanks

NO NO NO. First of all, you don’t need AP Bio for engineering (unless pershaps you want to be a Biomedical engineer?) Why not take AP Chem this year and AP Physics next year? Have you taken Calculus? If you have, then I would suggest Calc BC or Multivariable over Stats.

No. Doubling up on science AP 's is already pretty tough.
Can you take calculus instead of stats (much more important than stats for an engineer)?
Have you reached level 3 in a foreign language?
What are you taking this year?

AP Bio is good GE credit as it is the only course that knocks out the life science requirement (check the colleges you want to attend for their credit acceptance first) and triple sciences are a walk in the park if you have a science mindset.

Also, is compsci a useful/necessary class to take before college in my circumstance
