Former head TA (Jack) here - 15-213 still remains incredibly foundational to the work I do for my job. Working with the professors of that course (who also wrote the CS:APP textbook, which I still regret never getting signed by them!) was an amazing opportunity and something I hope I never forget. If you want some exercises to help you learn the foundations of computer systems, I honestly cannot think of a better resource than this!
