Next year, I will be a sophomore. I go to the best high school in my state and the courses are rigorous and very homework heavy. This year I took MST geometry, honors english, AP Computer science principles, AP human geography, honors french 1, and MST intergrated science, “MST” (math science and tech) is a class classification that is harder than advanced but easier than AP courses. I have all A’s so far. Next year i am planning to take MST Pre Calculus (I am taking algebra 2 over the summer), advanced english (my english teacher told me that i was very capable of going to adv), honors french 2, programming introduction, AP Euro, MST Chemistry, and i have an extra class space.
To fill this class space, should I double up on science so I can take MST Chem AND MST Biology in the same year? Do you guys think it would be too much?? If i dont take MST Bio, I will probably take Foods and Nutrition 
I also kinda wanna take AP Bio in my junior year and Physics in my senior but I dont want to drown myself in homework next year… please help!
Also, I plan to join two more clubs next year! I am only in one now.
