Bad idea. I tripped on 2C-E twice or thrice in high school and each time was very close to being horrific. You'll gain more of a new perspective on school taking it on your own time and contemplating the facets of socialization and social conditioning, pondering the nuances and differences/similarities between brainwashing and the education system, etc. than you ever will just being at school while tripping. That's why we have minds, we're able to think of and be in different places than we actually are. You don't have to be on a psychedelic in school to learn more about school on psychedelics.
What you'll experience is likely a combination of the following: awkward interactions with classmates you would never want to know you do drugs, let alone trip, let alone are tripping at the current moment / even more, if not 100x magnified awkward interactions with teachers and other staff who you of course don't want to know you're on drugs (and if you've done acid before, I think you can imagine the feeling of having to hide something in that state of mind, the extent to which the worry and anxiety can plague and ruin you) / small laughs and moments of relief from sharing what you're going through with friends / questioning of why you thought this would ever be a good idea / general anxiety and fear surrounding having to hide what feels to you as such a significant and huge thing as tripping / and on and on.
It's not fun. It's not insightful. It's not worth it. I promise, I've done it. Don't.
