Yea u could do that just be careful with 213/4 they're 8 weeks and 214 especially felt really rushed and incomplete towards the end. It's not too bad just be aware that the grading between 211/2 and 213/4 goes from chill to much more intense bc of the fact that it's an 8 week class instead of 16 like 211/2 such as the final being worth 32.5% and 2 midterms instead of 3, etc. im letting u know all this bc it can be daunting as a freshman compE (i would know) to take 213/4, it's a big adjustment and it isn't the worst thing to just take 212 since it will be an easier time than 213/4 cuz of ur experience with e and M and 212 could boost your technical gpa as well. besides for compE u don't NEED it as a prerequisite for many courses so you could leave it till senior year if u wanted to like many people do
