In my sophomore year I took 2 APs - World and Computer Science A, and had an A+ in World and an A in Computer Science A (5 on CS and 4 on World). However, this year (Junior Year), schedules just came out and I have a conflict between AP Statistics and AP Chemistry. I initially planned on taking AP Chem, Psychology, Statistics, and US History. However, I have a scheduling conflict between AP Chem and Statistics, which is very unlucky because I plan on majoring in either Business or Chemical Engineering. I’m leaning more towards Business so I plan to take AP Statistics, but I’m afraid I’m taking little APs junior year because I will be only taking 3 APs if I drop Chem for accelerated Physics. My dream school is Notre Dame, and it states on their website “As many rigorous courses”. I’m afraid taking only 3 APs junior year will bring my chances down. Any advice?
What other classes are you taking? Is stats your only math class? Are you taking a foreign language?
I’m taking French 4A because I heard colleges like to see that you take a foreign language all four years. I’m taking AP US, AP Psychology, Pre-Calc A, English 11A, Wind Ensemble, and presumably AP Statistics and Physics A.
It’s not the end of the world. Flip a coin and take the other senior year. As an FYI, you should have physics anyway for top schools and AP Chem for chemical engineering. But it really does not matter which order you take.
I agree that you have a solid schedule. Just be sure that you can get AP chem in next year if you opt to do stats this year if chemical engineering is still on the radar.
Most colleges do not give credit for stats whereas if you do well in chemistry they do. If you are considering chem engineering I would go with AP chem.
I’m considering Business more than Chemical Engineering which is why I feel AP Statistics is more important. Chemical Engineering would be my second option.
Take AP stats, save AP chem for next year. 
Here’s my advice. Instead of focusing your energy on one school, focus on your dreams and ambitions. Find a good list of reach, target, and safety schools that are a match for you. Even with top grades/scores, your chances are about 10%, which is lousy for anyone. Unless you’re one of the lucky chosen few, admissions is the only department where everyone’s job is to come up with excuses. One AP class over another isn’t going to be on their list of excuses.
