I had my 16 year old son do some individual SAT/ACT prep with PLZ before he took his tests, knowing that he needed some work on his verbal and writing skills. His tutor was really helpful in showing him tips and tricks, and his vocabulary skills advanced tremendously in a short amount of time. His first attempt at each test was pretty decent, but he pulled out a great score on the ACT the second time around. Thanks Parrish Learning Zone!
