I had a basic physics teacher that allowed notes and gave us a chest sheet of his own which literally listed equations, described variables and explained the situation you might want the equation. People still failed. In a basic thermodynamics class the teacher said it was open everything but the person next to you: laptops, internet, the book etc. For fun I took the test without either book or laptop and did just fine. Others found it hard. In both cases the problems required thinking about the situation posed and which basic principles should be used to evaluate the problem. In my opinion, cheating from internet access or outside resources is not the problem, cheating by gogling exact problems is.
