Effective Classes for Engineering Students

Hello. After my last post, I noticed I should be alot more fexible with my future. Right now i’m Deciding on how many engineering courses to take.

Junior Year
PreCal - Pre AP
Computer Science I- IB
Physics 1: Algebra - AP
Academic Decathlon (Permutation, Statistics and Algebra)
Academic Decathlon (Ecology)

Senior Year
Calculus AB - AP
Computer Science II- IB
Chemistry 2 - AP
Statistics - AP
Academic Decathlon (TBD)

Also (if it matters) I was thinking of. I want to do some kind of engineering that involves construction of somthing. While it sounds vague, I mean like mechanical engineering, not Chemical engineering. I’d like to get a masters, but for now, I’m just looking to finish my Bachelors.

Questions
Is this good engineering prep?

The reason I’m doing Chemistry 2 is that most schools (I’ve seen) require you engineering chemistry, or something like that. Should I Do Chemistry 2, or take Physics 2… or maybe Biology 2

I’m doing computer science because I’ve been told some schools count it as math credit. Could Someone Explain why?

I’m doing Calculus to see if I’ll like taking engineering courses in college. But before I take it, could someone tell me some examples of how Calculus can be used in real life? Just so I can start it next year with more motivation.

I wrote Academic Decathlon to know If i should really study the topic this year in math. Will it be relevant to college? Does it count as effective practice?

Should I waste my time with Statistics?.. Both of my years?

Oh yeah, I’m in 10th Grade

3 more questions

Does it seem reasonable that I could get out of college in 4 years?

Also Should I waste time taking the AP exam for Chemistry/Physics and Calculus? Since most schools don’t accept them for their engineering majors.

What else do you recommend for engineering prep?

Also don’t worry about History or Literature because I’m DC/AP testing out of them for college.

So… Maybe i’m in the wrong thread. Right?
