What Parents Are Saying...
"We've used Thinkwell for a number of years now, starting with Pre-Algebra and going up to Algebra 2. We all love watching Professor Burger's video lectures. They are long enough to explain things well, and he is not only a great teacher but also very entertaining, which is a huge benefit when trying to learn topics such as linear functions! The content is very rich. I like how there is a pencil and paper component to each lesson. All in all, a terrific program that we've been very happy to use!”
– Becky
"After reluctantly persevering with a couple of other math programs, we finally found Thinkwell. The humorous lectures are concise, easy to understand and delivered in manageable sizes. We don't have to endure the tedious repetition found in so many other programs. Having lessons online is a win for our family - this medium is so acceptable for the current generation. Doing the exercises online saves us a lot of time because the marking and correction is done immediately. Now that we've found Thinkwell we're staying with it.”
– Judy N.
"We have used Thinkwell for two school years now, 7th and 8th Math, as well as Geometry and Algebra 2. It is the favorite math program with both my son and daughter. They enjoy the teacher and his presentations, and feel they are very clear and complete. The few times we have been stumped and unable to understand, we have sent questions in and received prompt, clear answers. For us, Thinkwell has been a blessing, and we intend to continue to use it for the rest of our math needs. We have also shared this news with our friends, and several have also been won over to the Thinkwell side!”
