Fun example about lazy teaching: Our undergrad's HKN chapter kept a test bank of past exams in Physics, CS, etc. When I was studying for my Physics final I went back to past midterms and realized the professor recycled questions from previous years with some numbers changed up. I ended up filling my entire cheat sheet with the questions that weren't already on midterms but were in the test bank.

The result? The final contained a majority of questions from that cheat sheet. I still pose this scenario to a couple friends nowadays asking if this would be considered cheating, and the responses are actually a mix of "no, you're just taking what's publicly available" and "yes, you're manipulating the system to get where you are and taking spots from someone with academic integrity".

Just ask yourself. Did you learn the course well enough that you could have done as well without those questions saved?

As others have said, we go to college these days for a fastpass to middle class. If you haven’t needed the knowledge since, maybe you got what you needed out of the class and you worked the system in a legal way. Or maybe you paid a lot of money for that class and yet cheated yourself out of the knowledge you were paying to be taught. On some level it comes down to how you feel about it.

Since that class I've reached the conclusion that school is not the best way to learn concepts and materials but to learn how to work a bureaucratic organization to reach your own end goal (whether it's a job, ticket to the middle class, or simply knowledge), which in itself is a valuable skill. I think museums, seminars, and some NPR shows ended up being the best ways for me to really master the material I would've otherwise learned in school.

I think anyone who is naive enough to think that school is about anything but conformance deserves to fail. I did some courses before college and got a high grade and when I went there for my bachelor's degree, they didn't count that course towards my credit points, I had to do it again. In other words, my knowledge means jackshit at a educational institution. The only thing that matters is whether I can navigate the bureaucracy. Get that in your head.

> This is the side effect of lazy teaching. Unique tests cannot be leaked. Problem solved.

I have never heard of lazy teachers ever getting any consequences, so why should they stop doing these things? You could make it a part of their job, but of course lazy principals wont do that either. There just aren't any incentives to run a school properly.

The fact is few teachers at the university level are interested in teaching the majority of classes that students take. Some professors may enjoy teaching the higher grad level coursework, but overall professors are generally terrible teachers.

Teachers go to learn how to teach, in the abstract sense, for 4 years, to go to teach high school kids. They learn the techniques and tools to effectively translate subjects and educate people.

Professors do not do this.
