<p>To get into CHE 2A, you must take the Chemistry Placement Exam given during orientation. If you don’t pass, you’ll get placed in the workload class (WLD 41C).

<p>2A is regular General Chemistry, whereas 2AH is Honors General Chemistry, and I believe that is more accelerated and the class size is much smaller. </p>
<p>128 and 129 are primarily for Chem-related majors.

<p>If you have no Chem experience and pass the Chemistry Placement Exam with a required score, take CHE 2ABC and CHE 118ABC. 128/129 is, I’ve heard, pretty difficult, especially if chemistry isn’t your thing.</p>
