Exam guidance

Exam format and tool use

The problem-solving exam and MATLAB code-interpretation exam are held separately. For both, write answers by hand without running MATLAB or AI. Each exam is based on a 60-minute duration.

Problem-solving exam: Use the provided reference equations to build models and explain your calculations and the conditions applied.
MATLAB code-interpretation exam: 1 page of exam reference material is provided. Fill key portions of given code, find intermediate data and output values, or interpret graph changes. You will not be asked to write an entire long program.

For the exam time, location, and final arrangements, the information given during the lab session takes precedence.

Unless otherwise specified, answers may be left as fractions, radicals, or symbolic expressions. Draw graphs showing the axes, key values, and direction of change. Equivalent expressions and code with equivalent behavior are accepted.
