We've got CAT6's (California Academic Test) at the end of every year, and this year (10th grade) I take my high school exit exam.
I'm taking 2 AP classes this year where after you finish the course, you pay $80 to take a test and if ou pass, you get college credit.
Then to get into college, you have to take the SAT's which are the Standarized Academic Tests (I believe, I had an entire project on College Admissions and Affirmative Action last year
) which are extremely hard
