IIRC, in the movie Stand and Deliver, a score of ‘5’ is described as a perfect score. Is this accurate, or is a ‘5’ merely mean the testee is in the top (whatever)% of that year’s test takers?
I got a ‘5’ on the Computer Science AB exam in the late 80’s. Somehow I doubt that I got every question right.
In the Calculus AB test, getting at least 5/7 of the exam questions right gives you a 5. For the English tests, the individual essays get grades, and they use some kind of algorithm to figure out how much weight essays and multiple choice questions get ( I think essays are about 2/3 of the total score). Those are just the ones that I took, but I would guess the Comp Sci test would go something along the Calculus lines.
For all tests (except art) a five is the best you can do. However, rarely does this mean you got anywhere near a perfect score. On some tests you can get every single multiple choice question wrong and still get a 4 or 5 just by writing freaking good free responses (essays).
I would think the scoring levels would change each year depending upon the difficulty of the test.
In my day, you had to get a 3 to get any kind of credit. I got a 5 on the test I studied my ass off (Amer. History) and got a 3 on the one I just walked into cold (Eng. Comp.)
From my experience with the test, if you only do well on the multiple choice part (as I did with the English test), you can get a 3.
However, I have that sort of intelligence that standardized tests love to measure. God bless the SATs!
