Was worried to take this class because I took gen chem two years ago. This class was easier than my other lab classes. It was cool to meet a Latina chemistry professor. She was very kind and provided a lot of advice.

2BL is a lot harder than 2AL and your experience is based on your TA. My BL TA was great and gave feedback but my AL ta was not approachable. Communicated with professor via email and she was helpful and nice.

Halfway through the quarter she told the TAs to grade more harshly because the average was too high and it needed to be 87%. Her emails are passive aggressive, I do not think she likes her students. The final was a week earlier than the related gen chem series and was very difficult. Insane amount of time for so little units. Fun labs tho.

The final was extremely difficult with many errors, typos, and repeated questions. Her grading policy is harsh, and TAs are told to grade harshly. Very rude and aggressive in emails and when talking to students, and hard to reach. Avoid if possible (SBCC).

Professor was really nice during office hours and gave me some good advice. DO the extra credit. The class requires more work than 2al but its manageable. It's easier than the lecture classes and the final was fine. My TA for 2bl was a lot better than 2al so your grade will depend on your TA, Pazos doesn't grade anything.Try to get a TA that cares.

I do not recommend taking 2AL and BL at the same time as you mostly write lab reports in 2BL. Professor was very nice and helpful.
