<p>I doubt the test is even really required, since the OPUS system where you register for classes does not require a permission number or any prerequisite class to enroll in Chem 141, and the chem professors never actually check to make sure you’ve taken the test. It’s really there just for you to assess yourself, and even if a minimum score were required to allow enrollment in the class and you were only concerned about getting placed in it (which seems to be the case for the OP), it wouldn’t be hard to cheat on test.</p>
