Worried about college... (Acceptance, not lgbt issue)

I don't have anywhere else to really post this but I am getting more and more worried about my future in terms of college acceptance with my academics and such. I know a lot of you are in mid 20's and May have had some recent experience.

Let me just sum up what I have done as an incoming junior.

Freshmen: all academic courses, electives where all stepping stones to get into electives with prerequisites. Got a average of ~85. Mostly B's, one or two C's.

Sophomore: honors geometry and biology. Got B's in both of those. Rest academic classes that I got high B's or A's. One C. I also took intro to programming as well as Web Design I and II which I excelled in due to interest, all A's there.

What I signed up for junior year: AP Computer Science and academic everything else. With a couple extra electives such as personal finance and marketing.

I also have tons of volunteer hours and did freshmen soccer.

I'm worried that I'm not excelling enough to get into college. Should I meet with my counselor to do maybe honors Algebra II or something? I feel as if I might be underworking myself and colleges will see that. I also don't want a harder class to ruin my grades and such, but I feel as if I went on to do academic courses I would not be successful.

In senior I plan on dropping social studies and doing a regular math and science class along with AP stats and Astronomy (just because it is interesting). I'm not sure about honors/academic there though.

If my experience is crap, please tell me because I really want to go to a decent college. I plan on doing specifically plan to double in college for graphic design and computer science (web design hopefully).

And experience/tips/insight helps, thank you <3
