Overall, I am impressed with the content of the courses, the organization of the classes, and the learning experience. However, there are few things I find annoying and cumbersome. First, the number of emails I receive it's way too much. The communication should be in-app, not to my primary email. Second, having to purchase certificates and toolkits outside of the subscriptions. These should be integrated into the overall price; I find it misleading that I'm enrolling in a class, completing a diploma program, but have to pay extra for the summary notes and certificates. Third, the app doesn't seem to list all my ongoing courses, just the first one I signed up for. So, I have to find a workaround to access the course information.
