The students themselves are to write the questions into the comments section. Do it soon, and yes that means you. Then the students should practice these questions in their spare time, with the clock ticking. Ideally each question, or at least some of them, should come as a surprise. Don’t read them all until you are ready to give them a try.
Most people study to make themselves feel better about doing their work, and not to actually succeed in their chosen field of study. They spend hours staring blankly at sheets of paper. They should spend more time trying to solve problems or answer questions, usually under simulated exam conditions and with a clock ticking.
Tick, tick, tick…That’s the way to go, and yes I know it hurts.
