I highly recommend Charlene as an ACT prep tutor. Both of my daughters improved their overall ACT scores by 5 points and even scored 35s on some individual sections. In addition, they actually enjoyed their sessions with her as she made it relaxed, positive, and as fun as ACT prep can be. As an added bonus, she helped them a few times with pre-calculus homework problems with which they were struggling.
