Undergraduate student Open enrollment Completing incomplete Graduate student This exam consists of 35 questions. A maximum of 82 points can be earned. Partial credit will be given. There are a total of 13 pages, including the cover page and one blank sheet at the end for notes. If you need more space, use the back of pages. Write your name on top of each page! Multiple choice answers may be given negative credits if incorrectly answered. Avoid guessing! Petitions for regarding will be considered only if you have used permanent ink, unless an addition error has occurred. *IT IS YOUR RESPONSIBILITY TO WRITE LEGIBLE! No extra effort will be made to decipher your handwriting.
