One of my teachers gives his students essay finals. First, he tells us three numbers, A, B, and C. He gives us A essay questions to study before the test. He picks B essay questions to put on the test, and we must pick out C of them to answer. He tells us to study A-B+C of the given questions if we want to pass the final.

As a procrastinator, I only studied the night before. Luckily, some other students had taken the test a day early, and could tell me which of the questions the teacher had picked. Of course, the teacher would pick a different combination of questions to give to the rest of the students. After hearing which questions were given, I realized I needed to study N less questions than was necessary before!

Find N, generalizing to all possible A, B, and C.

To be honest, I had to work hard to improve my writing skills. Unfortunately, they didn't teach me that at school, so I had to do it on my own. At first it was difficult and I used https://www.bestessay.com/essay-writing-help/, it was my reliable support. This is where I did all my writing assignments. But by the end of college I was able to do the assignments on my own. And I was glad about that.
