Agree with everything you said. I also did the same thing basically, undergrad CS and grad math classes.
The author basically did all of undergrad math and physics, and now apparently they're planning to self-study all the grad math. The thing with self-studying is you're taking yourself out of the system, and at some point you have to inject yourself back in. I hope the author is able to do that and doesn't miss out on undergrad college too much, because it's really enjoyable if you find the right friends and you'll look back on it fondly.
