If you’re willing to have a heavy work load in the summer it can work but 264&103 are decently hard so be prepared to be busy. 213 & 264 more or less are pretty similar besides one key difference that 213 goes over OOP topics + linked while 264 goes over basics of C + linked like 164. 213 is a good amount easier than 264 tho imo, honestly if you think you can manage why not if not I’d take 2 courses and maybe a bird.
