Sometimes it comes down to just having shitty/lazy teachers as well. This is one of the reasons I was somewhat bitter about my college classes. There's two or three types of shitty teachers you can run into:

A. The teacher that went right into teaching at a young age and never really got much real world experience themselves. In some vast ironic conspiracy they're now trying to prepare hundreds or thousands of students for the very thing they know so little about. aka some of my illustration teachers. This is a huge fucking problem when the profession of illustration is mostly freelance work and these jokers don't do much freelance work themselves and can't teach you basic things like pricing your work, how to negotiate, how to stay on schedule, etc. They're glorified high school art teachers. I learned next to nothing important.

B. The teachers who probably cares and means well but the knowledge they're peddling is just too outdated and they're just plain out of touch. aka one of my graphic design teachers. We had all these computer labs for digital graphic design, but this guy insisted on teaching a class he's been doing since the 70s which relied on how graphic designers did magazine layouts before the advent of computer design. There was no greater understanding in the intricacies of graphic design by gluing cutouts and photocopies to large white boards over doing it in photoshop or indesign. It was a huge waste of everyones time.

Of course schools can also help you get internships...but that's a whole other topic.

The bottom line is just make sure you're learning something that's beneficial for your portfolio or degree. Whatever an employer finds more useful.
