The exam used by the UNLV Chemistry Department for placement in general chemistry CHEM 121 is the California Chemistry Diagnostic Test. This is a multiple choice test, consisting of 44 questions which will assess the student's level of preparation in chemistry, as well as basic mathematics skills. In order to register for CHEM 121, the student must achieve a score of 22 correct.

Times and locations for the exam may be found at the beginning of the Chemistry (CHEM) listings in the UNLV class schedule.

The time allotted for the exam is 45 minutes. Calculators are allowed. There is no penalty for wrong answers, so it is better to guess than to leave an answer blank.

If a student does not achieve a score of at least 22 on the test, the student will be required to take CHEM 103 and achieve a grade of at least "C" (NOT "C-") in order to satisfy the prerequisite for CHEM 121.

The student may not repeat the Chemistry Placement Exam within three months of taking it. After waiting at least three months, the exam may be repeated ONCE ONLY.
