"Five Stars. This is a truly exceptional learning tool. As an adult and first time college student I really needed to review everything for the TSI math test. I am so happy I found this, it is definitely more than I expected."
Lala

"I always have struggled with math, and now that I'm preparing for the TSI I've been in search for a tutor. This site has given me the tools I need to succeed in math. I'm so happy with this site. I realize now that math is not that difficult and that I'm smarter than I thought."
Mina

"I've been out of school for a few years and am going back to college next semester. I have to take the TSI test. Upon reviewing the practice material, I realized I had forgotten just about EVERYTHING. This program goes through everything step by step, allows you to quiz yourself, shows work for problems you don't understand, and see teachers work out problems on a white board. The teachers are great, and one of the teachers gives you this adorable smile at the end of all of her videos...melt. I feel much more confident and prepared for my TSI test now! Plus it's kinda fun."
