That is SAT test prep courses specifically though. Not going in completely cold versus having prepped for the test. I mean, if I took the SAT today many years on, I'm sure I wouldn't do very well--at least on the math section. There's too much that isn't muscle memory any longer because I haven't done a lot of the high school math stuff in years.
Certainly. My point was more though that, while I could hopefully reasonably puzzle my way through a SAT test without doing any prep, I doubt I'd do a very good job within a time limit because I'd be puzzling a lot of things out that I learned decades ago and haven't really used since without checking a book out of the library and spending at least a few days with it..
