CS202 Midterm Exam - October 9, 2025

This was a pretty run-of-the-mill Dr. Plank exam.

Here is the mapping of scores to letter grades. I don't put plusses and minuses on the grades. Please see https://web.eecs.utk.edu/~jplank/General-Teaching/Final_Grades.html for how I map exam grades to final grades. This semester is different from previous semesters because there are two midterms. This is the first of the two.

A+: 88-98
A: 78-88
B: 65-78
C: 49-65
D: 38-49
F: 0-38

The exam was in person, pencil and paper, no technology. For several questions, I had 10 different sets of questions, so this link is to an example exam, as everyone's exams were different: Exam.pdf.
