AP classes for senior year and mvc

<p>Hi, I'm junior in highschool, and working on my senior schedule...
Is it crucial to have full schedule with difficult classes??
I had AP Eng AP Stats AP Calc BC AP Physics B and AP Chem</p>

<p>Next year, I signed up for AP Lit AP Euro (love the teacher) AP Comp Sci, Spanish 3, and Online Econ/Gov (1 sem each), and Decathlon..
I'm going to self study Physics C and Econs on own.. This will make 12 AP tests total, but 8 AP Classes in highschool..
If I take AP Gov (with Honors Econ for 1 sem), it would make full schedule to sixth period.
It would help me in GPA (I'm now 5/600 in class), but I have 8 classes right now including swimming and it's so stressful. I'd like to focus on work, clubs, and decathlon next year without giving stress on my school loads...
Is it cruical to not take AP classes when your school has the AP class? We can have 7 classes on campus but I'd like to take 1~5 period on campus with online (I want 0 Per, but doesn't have any AP classes.. Maybe TA or student store?)
There are AP Psychology (online only) AP Art History AP Music Theory offered at school for other APs.. Help me with schdule first ! I'm majoring finance or engineering or math.. My reach is stanford</p>

<p>Also, I'd like to take Multi Variable Calculus class.. I heard college near us only offers it in the morning when I'm at school... What would be an another way to take a math beyond calculus bc (MVC, linear algebra)? Should I take it through EPGY online class which I have to pay 3k for year? Is there anyone who'd taken the class at local college? Do you guys took it for night classes??</p>
