Good for standardized test preparation.
This is a great site, especially for ACT prep. This site provides a good, overall review of the ACT test. It is an excellent source for ACT test prep for students.
How I Use It
I use this site to prepare students for the PSAT and ACT test. Students are asked to work on and discuss the quiz questions and compare their reasoning to the site's. The students at my high school are encouraged to use this site to study for the standardized tests. I have seen many students improve their readiness for standardized testing by using this site.
