Is there a good online course that covers computer architecture at an undergrad level?
I just finished 8th grade. I know a bit about computer architecture and logic gates, but not a ton. I know the basics of single-variable calculus and linear algebra, and I program a decent amount, mainly in Python 3, though I have experience with versions of C (used for Arduino, for example). I have looked at Assembly code but never programmed in it.
I'd like the course to be decently cheap, and it would be nice if it has a sense of legitimacy such that I have a shot at getting it to count for credit/go on my transcript.
Any recommendations would be appreciated. Thanks!
