@Orangered123 IIRC you have C++ experience, the class will be a breeze for you. It is taught in Python, and is loosely modeled after the Berkeley course. Although you already (possibly) know it articulates there the reason I say this again is because he does not directly go over material as you would if you took 61A at Berkeley, so he offers optional things to read through if you would like to be more in tune with those who take the course at Berkeley.
He has posted every single assignment due for the semester online, you can redo any assignments until you get full credit; showing up to class is optional. There are certain times where he has in-class activities so those would be a good time to go for points. There are no quizzes/tests, but there is a programming project due at the end of the semester that you have to present.
