Courses Completed: Linear Algebra

I completed the Linear Algebra course as a prerequisite to an M.Ed program in Mathematics. I worked entirely at my own pace, it was cheap, I actually learned the material. This was not a "pay your fee, take your B" type of class. I had to demonstrate true understanding in order to earn credit. Dr. Curtis was responsive and helpful when I had questions. All in all I would recommend this course and any other Distance Calculus course.

You don’t just learn in this course you understand. As someone who has always struggled with math taking advanced courses was intimidating. Dr. Curtis and his TAs made math manageable and framed the questions in a way they were applicable to real world. Thanks again!

Excellent course that you can take at your own pace. The instructor is excellent and I was able to get my questions answered quickly and complete this for an EMBA prerequisite. I would recommend this course to anyone trying to learn basics of calculus on their own timeline. The class prepared me well for my coursework at MIT.

Courses Completed: Calculus I

After two failed attempts at my university, this course helped me understand Calculus. The live maths tool along with Dr. Curtis were especially helpful, allowing me to visualize concepts and expand my understanding. The explanations were clear, the examples practical, and I could learn at my own pace, which built my confidence. Thank you.
