Insights into Chemical Engineering program

<p>I got admitted to Cal as Chemical Engineering transfer student. Can current and former students give me some insights into the program? What are the difficulty of material, homework difficulty, and exam difficulty of ChemE classes, such as ChemE 140, 141, 142, 150A, and 150B?
Also, what topics in math, physics, and chemistry are frequently used in ChemE classes? I will spend this summer reviewing materials to get ready for Cal.</p>

<p>I’m not Chem E, but my roommate was (notice it’s a “was”, not “is”; she switched to MCB last year).
From what I understand, it’s a lot of early morning classes, at least one 5 hour lab a week, and extremely difficult. Chem E is also a very small major because of all the “weeding” out. Sorry I couldn’t give you any more information, but good luck! </p>

<p>Biology 1A and 1B lectures are traditionally held at MWF 8-9, while organic chemistry (3A, 3B for biology majors, 112A, 112B for chemistry majors) are traditionally held TuTh 8-930. This apparently has been the case for decades.</p>
