i'm in college now, but i took the ACTs when i was a senior. i did really well the first time, and didn't want to take them again.
my experience is that they were easier than the SATs, but that you had to cram more questions into less time, which was fine for me because i don't have a problem with taking tests. if your'e a bad tester, however, this may present an issue.
