It's great, super helpful and informative. Breaks down complex concepts so that they're easy to understand. A couple things I would change, on the mobile app I couldn't find an option to change the video playback speed. Also, I must say I was pretty pissed off when I found out that to take a test for credit on a completed course the subscription which is already quite expensive especially for me as a student has to be upgraded again. Just some suggestions!

Very convenient, easy to use, but very frustrating!!! I'm allowed to retake it 2x, total taken is 3. But on my second time taking it, it doesn't give me the highest score I earned, it only shows my first score. I retake it multiple times after, but the high score is never shown! I check grades and it still gives me the lowest scores. So frustrating!!!

Excellent app! Awesome way to access your course studies on the go! Literally just did a Quiz on my phone! Update: The app sucks. It's not as good as I thought it was. It doesn't even have the same functionality as their mobile website. No ability to save lessons. No ability to increase lesson speed. And it BUFFERS all the time for some reason, compared to the website which never really buffers. In comparison, the mobile site is EXCELLENT. The app is just "okay".
