First of all, if engineering is what you love, then choose that, no matter how difficult it is. My dad would love for me to do something with business but I'm a science girl, so, no matter how difficult it gets, i'm going to do what interests me and only me. When the time comes, your mom will support you.
1. Honors Government (It will allow you to focus more on your other AP's)
2. I have been told that AP computer science is a joke, is it possible for you to do a dual enrollment and take an actual science course at a local college?
3. Physics C requires some calculus, but I'd say choose that one
4. Continue with French
5. STEM Engineering
If you cant do a dual enrollment class for computer science, what you could do is take
AP Biology or AP Chemistry.
Here is the thing, if you start college and suddenly decide that you want to major in accounting, it is so much easier to learn the subject since the foundation is much different than engineering. It would be smarter to focus on engineering during high school so you can be prepared once you start college.
Hope I was of some help!
