1) Yes, but most universities won't consider your application complete until they receive everything, including your transcript and SAT scores.
2) No.]
3) Probably, but most universities will require your counselor (or you) to send a mid-year review and a final transcript.
4) No, but I hope you've taken it before, if this is your senior year.
5) It depends on the teacher, some of them will and some won't. Mine let me read it

6) In college, you make your own schedule, and you can pick Monday/Wednesday/Friday classes, which are 50 minutes long, or Tuesday/Thursday classes, which are an hour and a half long, it's up to you. Sometimes you'll have strange gaps in your schedule because certain classes are only offered at certain times, but I usually use the breaks to study or eat.
Class size depends on the type of class (and the university you go to). At most state schools and big universities, introductory science classes tend to be huge and might be 100-300 students. Class sizes get smaller as you get into your upper-level courses; honors classes and seminars will be on the small side. Average class size at my university is about 40-50. My honors classes have about 15-20 students.
Introductory classes and general course requirements, you'll be with a mix of majors. The cool thing about college is that every class will have a mix of freshmen, sophomores, juniors and seniors - it's not like in high school where you're with all the eleventh-graders or all the 12th-graders. Depending on if your school has an honors program or college, there may be honors courses offered (my school has an honors college, and the honors classes are always smaller and much more discussion-based, which is awesome, I love them.)
7.) Haha, the freedom part all depends on you. If you're dorming or living off-campus, then you're on your own. Sounds like a good thing until you realize how homesick you are (or if you can't cook, lol.) There's no one to tell you what to do, which can be a good and/or bad thing, depends on the person. My roommate last year was definitely not the most self-motivated student, and she was used to her parents reminding her to do her homework. There wasn't anyone at college to tell her to do that and she ended up failing a class

' I enjoy my independence at college (I go to school five hours away from home) but I donmiss home and my mom's cooking.
