Sample Midterm 1
INSTRUCTIONS: There are 3 parts in this test and you must do all of the questions.
Aids allowed: calculator. You may leave your answer expressed as a fraction or a factorial or power or sum. There are a total of 100 points, so you should allocate approximately
1 minute per point. The points for each question are written in square brackets, e.g., [8 points]. Time may be a factor, so be very careful in allocating your time. Be sure to show your work and reasoning, not just your answer. Partial credit will be generously awarded, so make sure you try all parts of the questions. Obviously, grades will be higher for more precise, detailed, and focussed answers. Be concise in your answers. Good luck!
