Hi everyone. This fall I’ll be a junior in High School. I have a lot on my plate like standarized testing, 4 AP classes, applying to programs,etc. I was wondering if you all had any advice for me/ HS juniors in general tips for being able to manage everything on our plates while still getting 7 hours of sleep. Thanks !!!
Do things early and plan well. I took the SAT in October when I was in the middle of a heavy courseload (got 1330). I then took the ACT in February and again, too much school work to really study (got a 30). I then waited until after AP exams to take the ACT for the last time because all my AP classes became pretty much dead (with a month of school still left) and literally the only academic work I had to do for a whole month was ACT studying. I printed out practice tests and did them in class or at home for a whole month. My schedule allowed me to devote myself almost religiously to the ACT. I managed to bump my score to a 34.
Honestly if you plan well you will have no problem getting enough sleep. I managed to keep my social life, my grades, keep up with sports, and managed to be in bed by 9 PM every night (of course, the time I stayed on my phone in bed AFTER 9PM is another story… 
Get a daily planner. Do things during lunch when you can. If you have a light class one day, get some work done for other classes in that class. Do the homework like you mean it so you don’t really have to study when the test comes around. Go to teachers for help during lunch (it will also help you get on their good side). The school library and public library will have dozens of study books on each class/AP subject (also on the ACT/SAT). They are free resources, so use them.
If you have National Honor Societies (mine has societies for art, math, science, spanish, chinese, social studies, etc.) then use them. I am part of three of them and my job is to tutor students during lunch in those subjects. Honor Societies have people who already took the classes you’re taking and they’re knowledgeable on the subjects. Go in for tutoring if you want.
Most importantly, stay informed. Deadlines can pass without you knowing about them. Your school probably hosts helpful programs throughout the year, especially for juniors (like college visits). Get in touch with your guidance counselor at the start of the year (especially good to become familiar with him/her - they’ll be writing one of your college recommendations).
