<p>Someone told me that the chem series (the one im taking specifically is chem2a, 2b, 2c) has to be taken in consecutive quarters, and if I took chem2a last quarter but can’t this quarter, then I have to retake chem2a again. Is this true???</p>
<p>It has to be taken consecutively as in 2a is a prerequisite for 2b, which is a prerequisite for 2c. In other words, you can not take the classes out of order (2a, 2c, then 2b)</p>
<p>You don’t have to take the classes in consecutive quarters. As long as you took Chem 2a at some point in time, with a passing grade, you do not have to retake it.</p>
