I accidentally started the lSAT prep instead of SAT prep earlier this year, and I really liked how (on the lSAT prep) I could set my final score goal and it would work me toward it. Also, the "trail" diagram on the side which helped me see where I stood in progress was a super helpful visual. I thought it would be awesome if you added those same features to the high school SAT prep to aid students in seeing where they are and where they want to be.
