I shouldn't worry, regardless of how I did in class
I do very well on standardized tests, but do....decently in school (ADD, I cannot physically listen and fully understand lectures).
I took them once in seventh and eighth grade as it is used as the qualifying test for a camp I wanted to get into (and loved). The first time in high school, I felt I could do better, and I did
EDIT: I've heard that the math, science and history SAT2's usually balance out with the equivalent AP tests in that the AP tests go into more information, whereas the SAT2's focus less on how much information is tested, but on how well you understand the concepts they function on. For example, there would be alot more different kinds of chemistry concepts on the AP test, and alot more things to remember, but the SAT2 would test how well you knew the concepts it did test harder than the AP tests questions on that same topic.
My school doesn't offer AP classes, and I have enough things to study for without signing up for AP tests, so I do not know for sure. But among the people I've talked to is someone who helps scoring the AP physics test....Any info on this?
