There are no makeups. All exams are given only once. The exam dates are announced in advance, so everybody has an ample chance to resolve any schedule or study load conflicts. In case you have a personal or medical emergency, you can use your option to skip one exam. I believe in equal testing conditions for every student and do not want to offer advantages to people who invent excuses to manipulate their exam schedule.
All exams are closed books, closed notes.
This helps keep the exam problems as simple as possible. Usually, calculators are not even needed for most problems. Calculators are to be used for computation only, and not for storage of information. If you have a fancy calculator, you cannot use pre-programmed formulas and graphing functions. If you have other questions I did not cover, please let me know.
