I am a Psychology major and music minor. I just finished completing the tasks on this site about ten minutes ago to see how and what they tested. Not only this but I was able to test myself on what I have learned in my own music theory classes. This site was a wonderful way to learn or retest what you already have learned. It was very simply stated and easy to follow. Being in music theory classes myself, I found the information of the content to be quite accurate. This site would be an excellent way to teach music theory and to test students on what they have already learned in class.
This site was easy to navigate and to use. The pop ups for the tests loaded a little slower than most other things I have come across but were very easy to use and helpful once they did open (worth the wait). Other than that I did not really run into any technical issues at all. This is a very helpful, organized, and easy to navigate site.
