<p>CHEM 111 is intro chem for engineers; CHEM 105 is the equivalent for science majors. If you’re an engineer you’ll take CHEM 111/ENGR 145, if not, then CHEM 105/106.</p>
<p>I got a 4 on the chem AP test and opted to retake CHEM 106 (while keeping my credit for 105 & 113). Big mistake; the class is complete review and a waste of time. Go straight into ochem.</p>
