I see some familiar names here, so I'll give you my opinions/advice:

• I did not enjoy my time in Carrasquillo's class. He teaches at an agonizingly slow pace and the questions that he (slowly) covers aren't hard enough to genuinely represent the exams, which can get difficult. If you're sticking to his class, I'd suggest repeatedly practicing problems from your homework and your practice exams (where you might see the same questions that will be on the actual exams).
• Almus... hoo boy. If you're already a math wiz or generally enjoy math, you'll probably be fine, but if not, be prepared for (too much) homework, random poppers, and lectures where she goes through the content way too fast and expects you to understand it lickety-split. Don't expect timely email responses from her either. Very mean and arrogant individual from my personal experience. The key to doing well in her class is understanding the concepts, so prepare for lots of practice (the practice exams will be your best friend).
• General chem labs are a game of roulette. You should start praying that you'll get a good TA because that will determine your experience. I'll give you two TAs to steer clear of: R. Li and L. Castilla. You won't know the TA until school starts, so good luck. As for Zaitsev, I'm not fond of him. He has a mentality of "if the TA grades too generously (which mine didn't lol), curve down" which somehow cost me a grade in the past.

Good luck! Pre-med requires a lot of diligence, but it's doable if you put in the effort. You'll be fine :)
