I had an very relaxed Indian professor who served as as department chair when I went to university and he always had open book/note quizzes, tests/exams with no restrictions. These exams weren't designed to be more difficult, some answers you could very quickly reference from the associated text, handouts, or your notes.

People asked if he was concerned that people cheated or wouldn't learn anything and he once gave an insightful comment m that stuck with me: if people cheat, and they will, they're only cheating themselves.

He was right because while almost everyone passed his classes, not everyone ended up with successful careers. If they did, they probably had to pickup the sort of knowledge he crafted together like a masterful chef and hand fed us. The education is the product, not the degree. The degree is often a necessary rubber stamp to get past the first interview filters but it's not going to help you in most positions for the subsequent interview or actual job demands. You're really only cheating yourself of the education because the education is the real product here.

Things have changed a bit and you can find pretty much anything online readily, but you have to chop up the information, prep it, and craft it into a meal. Over time these skills improve and you too can become a knowledge chef but your (good) university programs give you the tools to become a knowledge chef in your field. They start you out as a cook who knows how to do certain things but they also give techniques you need to make your own new dishes. That's what you're paying for.
