<p>Chem 1B builds upoen Chem 1A. Chemistry, like Physics, is a foundational course. You can’t go into orgo without learning Gibb’s Free Energy. And you can’t learn the 2nd Law of Thermodynamics in 1B if you did not understand the 1st in Chem 1A. </p>
<p>1A + 1B are strongly linked together. I looked over the exams for Chem 1B. It’s not that hard. 96 questions in 180 minutes. Most of them multiple choice. Be prepare for the competition though. You’re in a class full of PREMED. Most of the PREMED will be asian girls. So good luck to you. The chem core is usually the weeder class for the wannabe doctors.</p>
