Chem 210 Practice Exam 4A Page 1 of 20 Organic Chemistry: Chem 210 Practice Exam 4A There are 35 questions on this exam. The actual exam will be shorter (no more than 30 questions). Check that you have done all of the problems and filled in the first 35 bubbles on the scantron. Most questions are worth 4 points; there are several two-point questions clearly labeled in the text. The maximum score on this exam is 124 points (the actual exam will be worth 100 points). Instructions Answer sheet 1) On the scantron, you need to clearly fill: y o u r name and your student number , section number Section 001, 12:20 pm lecture Section 002, 3:35 pm lecture test form (white = test form A; yellow = test form B; blue = test form C, green = test form D). 2) Use a #2 pencil Exam policy 1) No electronic devices of any kind, such as calculators, cell phones, or even more advanced digital watches, are allowed.

If necessary, the values from the provided tables should be used, even if they differ from values that you may remember from different sources. 6) The exam results are based strictly on scantron’s marks. No extraneous information is used to adjust the scores. Mark your choices with extra care. 7) You may not take the exam with you . You may copy your answers on the provided page and compare them with the answer key. The answer key will be posted on the web after the exam (under "News").
