In junior year I am planning to take Spanish IV, Web Page design HTML/Intro to Javascript, AP English II, AP US History, AP Calculus A/B (as a 0 period, and the teacher and class is very very very hard and time consuming as many have said), and AP Chemistry. That leaves one space for a class left....should i do tennis or not? I'm doing it this year (9th grade), and next year too (10th grade). Not going to do it in senior year though...should I continue in 11th grade with the above schedule of classes?
