We have been using Instantcert for several years now in our homeschool. My boys have used it to study for various CLEP and DSST tests with great success. I love being able to check the discussion boards to see others' experiences with tests to best prepare my own kids. I have referred everyone I know who is preparing for CLEP/DSST tests to check out Instancert. We love it!
