Rigorous High School Schedule?

Hi, I go to a school where you generally have to take intro level courses before APs (makes sense), but they allow students to take AP Chem automatically- as long as you have taken intro physics. So most students take(grade 9 to grade 12), intro bio, intro physics, ap chem, ap some other science. The thing is, I transferred into the school not knowing this option existed, so I took intro chem as a sophomore. Now (since I want to take all 3 sciences) I have to take intro physics as a junior. (Then AP Physics as a senior)

I really want to go to MIT- its my #1 choice. My concern is, most of the students who get into MIT from my school(which is pretty prestigious i guess) take advantage of its multitude of advanced science options.(ie out of the MIT acceptees this yr all of them took ap chem, ap physics, and electronics/robotics) Would I be at a serious disadvantage if the only real ap science I take is AP Physics Senior yr? MIT is a really sciencey techy school so I’m worried. >.<

There’s also the fact that everyone says “take the most rigorous courses available to you at your school” and its clear I haven’t done that because I did not know I could take ap chem! Is there any way I can dig myself out of this hole…?

Thanks

i guess if you wanted to amp up your course rigor for junior year, you could take a second science (electronics/robotics would look great on your transcript). or you can see if theyll let you take some other ap science (perhaps ap bio since youve already done intro bio?) this year. either way, if you get rejected from MIT it will NOT be because you missed out on one ap science class. just do as well as you can in your other science courses and test scores, and if you really want to, add another science for junior year. good luck!
