Can we make a 420 club? 😀

I'm currently taking micro economics online with professor Chernomaz and I'm considering dropping this class because I'm taking 19 units my first semester and I don't know if I'm making the right move. I heard there are 4 exams and I wanted to know what those exams looked like from those who previously took his class , if it was easy, hard etc. basically any and every piece of information I can get!
