Video Tutorials for Difficult Courses

Macroeconomics, Financial Accounting, General Chemistry, Principles of Physics, and Basic Statistics are among the most difficult courses here at AU. If you are struggling with any of them, you can get extra help here.

On this page you will find a series of video tutorials performed and designed by our Supplemental Instruction (SI) Leaders* to enhance understanding of the complex topics covered in these courses.

The first series deals with Macroeconomics concepts and problems. More tutorials in other areas will be added in the near future.

If you have questions or suggestions to improve this page, please contact us at:

*ASAC's Supplemental Instruction (SI) Leaders have successfully completed the courses, they know the subject material, and they are trained to help their fellow students. If you think you would benefit from attending an SI session, check out the SI schedule.
