“Enjoyed the Class and Its Format”
I really enjoyed this class and the format it was presented in. For me, I learn and retain much more through an online class due to the fact you can do the course as an 'open book.' This really makes me search for the answer and in return, I retain more information. I found it relaxing to be able to turn in the work on the assignments and tests at my leisure and when I had the time. I liked the fact you were very clear that more internet research may be necessary for some assignments. To be honest, there is nothing that I disliked about the course. I will definitely be taking another online course from you!
