Following up on my previous post about high school classes to prepare for college, here is some information about pre-college testing. There are two different standardized tests that colleges use as part of their admissions decisions. Fifteen years ago, some colleges and universities preferred the SATs, others preferred the ACTs, and some took either and/or both. Apparently that has changed now. At my first high school, enough students went to either school that we were encouraged to take both. Here's what I know about these tests.
