A PSAT/SAT Prep class is a program created to help kids, like us, to prepare for the PSAT and/or SAT tests. There are two parts: reading and math. These classes are small and usually consists of 4-16 students. The teachers work hard to provide the students the knowledge they need to ace the tests that they will eventually have to take to go on to college. Sometimes you have to pay to take one of these classes and sometimes, they're free.
