Dear IL'ites,
Induslady asked me to conduct this month's contest. Coming after Jenz who so admirably conducted the Nov Book review contest, I have big shoes to fill. It's a puzzle. Here you go!
In my introductory economics class, the professor said here is how marks and exams work for her course. - 50 marks for mid-term exam
- 50 marks for final exam
- Total above 90% is an A grade. Below 90% is a B grade.
However, taking the mid-term is optional (i.e. students can skip it). Students have the option of making the final exam mark count towards the entire 100. Mathematically, - If mid-term marks < final-exam marks, then total marks = 2 x final-exam marks
- If mid-term marks > final-exam marks, then total marks = mid term marks + final exam marks.
Following are the questions for you..
- What is the professor trying to achieve by making mid-term optional?
- Why didn't she make the final exam optional?
- What type of a student will skip taking the mid-term exam?
Assume that a student’s motivation is to get an “A” grade. For a student, only grades matter, not the actual marks. Assume teacher’s motivation is to make sure students understand the content of the entire course.
