    CHEM2AL . Pazos S 3 Months Ago

    This class difficult but Pazos honestly is not that bad. The biggest affector of your grade is if you have a good/easy TA or not. Many student have to take this class which is why Pazos is so strict on attendance.

    The lab itself was kind of fun but lab reports were tedious and time consuming. Make sure to double check your lab report grade because sometimes you get the correct answer and still have it get marked wrong. The final practice questions she provided were extremely easy and not at all like the exam, which was almost entirely about acids and bases.

    CHEM2AL . Pazos S 4 Months Ago

    Labs are fun, and usually don't take most of the class. Grade can be curved down but a majority of your grade depends on things done completely on your own time, so if you know how to read instructions it's not hard to do well. Final was very simple and does not require much preparation for a good grade.

    The labs are easy, you have to go above and beyond to get a "perfect grade", the TA's are meant to grade super harsh. 9 out of 25 assignments got perfect score. Reports and pre labs took HOURS. If your classes average is too high, prof will curve your class down. I ended with an A after the final and got a B+ bc of the curve down. Im so irritated.

    The class depends entirely on how harsh your TA grades your lab reports, but it is unclear what is actually expected in each one. I got point off for "writing too much" yet it was still under a thousand words. The final is ridiculously hard.

    So much work and poorly organized course materials. Communication was poor, never interacted with the professor but her syllabus makes it clear she is not accommodating. Great course to take if you want to convince yourself you hate lab.
