The Department of Mathematics, Applied Mathematics and Statistics offers proficiency exams for Math 121, 122, 125, 126, 223 and 224. These exams are given twice each year, shortly before classes start in the fall and spring semesters, on a schedule determined by the Office of Undergraduate Studies (*not by the Department of **Mathematics, Applied Mathematics and Statistics)*. The next date the exams will be given is January 6, 2021 from 1:00-4:00pm (Eastern time). The deadline for registering for the exam is December 31, 2020. **Proficiency exams are NOT given at other times! Students are expected to research these scheduling issues BEFORE registering.**

It is not possible to complete two proficiency exams in a single three hour period. Students who wish to test out of two math courses will have to do this by taking separate exams in August and in January. Students are allowed only one attempt at a proficiency exam. If you do not pass, you will need to take the course.

To be certain that an exam is available for you, you** must **register for a proficiency exam in advance (*preferably at least 24 hours in advance*) by contacting Prof. Butler. (*If no one requests an exam for a particular course, an exam for that course may not be available. If the number of students who show up for an exam exceeds the number of available exams, those who registered in advance will be given priority*.)

A description of the material covered by each exam is provided below. There are not sample exams available. The point of these proficiency exams is to provide students who believe they know the material an opportunity to demonstrate that they should be excused from the corresponding course. The Math proficiency exams are similar to the final exams given in each course; problems are modeled on those of past course exams and on homework problems from texts used in these courses. To receive proficiency credit, your performance on the exam must be equivalent to or better than a C grade in the course (*in the neighborhood of 70%*). Proficiency credit is indicated on your transcript by the symbols PR; no letter grade is given and proficiency credit does not count as part of your GPA. There is no penalty, and no permanent university record, if you do not pass a proficiency exam.

You are not allowed to use your own formula “cheat” sheet. You need to supply your own calculator, pencils and erasers. There are no restrictions on the kind of calculator you use for the exam, but computers, smartphones and other devices with communication capabilities may not be used during the test. You may use the calculator to do routine arithmetic computations only. All details of differentiation and integration must be shown. You may not use your calculator to store notes or formulas.

You might consider the following factors when deciding whether or not to take a proficiency exam:

- You may not learn very much in a class if you already know the material well enough to pass the proficiency exam. Passing the course by proficiency will free up your schedule so that you may take another course in its place.
- You only get one chance at a proficiency exam, if you do not pass the exam, you will need to take the class.
- Many students may start at the second or third course of a sequence after skipping earlier courses by proficiency. Some of these students have difficulty adjusting to the demands of a college course. While most students make this adjustment in a few weeks, some never do and struggle through the entire semester. In a worst case scenario, you might drop the higher-level course and decide to take the lower-level course for a grade the following semester. This would actually put you behind a semester since you could have just taken the lower-level course initially.
