Today was the final exam for the class. The structure was similar to the mid-term exam. The exam was divided into four sections: Graph Theory, Cryptography, Congruences, and Modular Arithmetic. Each section contained four problems: 2 C-level problems, 1 B-level problem, and 1 A-level problem. The C-level problems are problems that I expect anyone in class to be able to understand and answer. The B-level problems are intended to show students have a solid grasp of the material. An A-level problem shows the student knows the material well enough to apply their knowledge in new ways or to extend their thinking beyond what was done in class.
All students need to complete at least 6 questions and they must also complete at least one question from each section. This prevents students from dodging an area of weakness. A minimum of 9 questions must be completed in order to receive an A on the exam: 6 C-level questions, 2 B-level questions, and 1 A-level question.
There was a total of 90 minutes allotted for the exam. Students began finishing the exam after about 50 minutes. About three students took 85-90 minutes to complete the exam.
In general, students seemed okay with the coverage and difficulty of the exam. As one student said, "It didn't make me cry." That's a good thing.
