The videos are very good and quizzes but there's still a lack in anatomy videos. My main concern at the moment is that I had won in a raffle free prime for three months and apparently before last week I had "used up all my videos". However, I couldn't take my time to ask about this at the moment because I had a really big test coming up in the next few days so I decided to just then and there pay for the Prime membership because anyway I was thinking of purchasing it when my three months would've been up because the videos are super helpful and necessary in my study routine.
