I hope it goes well for the little rascal. I’m still a bit bumped from finding out that Marsupials are also Mammals — first found that out years ago, but when I was a kid they were considered separate. Same went for the change in status of Protista, that bugs me a little. :^)

Worst part of going back to school later in life isn't learning new information; it's having to learn the new classifications and renamings of old, information, already learned. Had some problems with some adult classes years ago, until I realized they were using revised terminology to "teach" me what I already knew.
Over 25+ years of hospital work, I had to keep relearning new terms for old things, e.g. bed sores uh pressure sores uh decubitus ulcers uh ...; oh, you get the idea.
None of it did anything to change prevention, diagnosis, or treatment; but lord help the hapless care giver who used other than the current terminology. Now, 20 more years later, I have no idea what they call them.
