Dr. Piatt is a nice person but her class is extremely hard. I had to teach myself for the whole semester. Homework doesn't relate to tests at all but it counts for overall grade so it's required. She has high expectations for her students shown through her tests, students must understand the materials and concepts 200/100% to score at least a 70.

Professor Piatt is very nice and helpful in understanding course material. That being said, the required course material is very demanding and requires a lot of outside studying and learning. Tests are the biggest challenge of the course as they are concept based while most homework is calculation based

Professor Piatt is nice and if you seek help, she is very helpful. The tests are extremely difficult, and the homework is long (I would like to note that she has shortened it since the beginning of the year when it was 50ish problems per week). The class is simply very difficult. Be ready to study a lot, but if you put in work, you will be ok.

I love Dr. Piatt. Many people give her bad ratings but that is just based off of the difficulty of this class. She is very enthusiastic and clearly wants her students to succeed. Lectures are engaging and she will always answer questions. Only downside is incredibly hard tests but she curves and offers extra credit.

Dr. Piatt is a super nice person and makes lectures fun and interesting. That being said, she assigns 30-question homeworks that are around 90% short-answer problems that are either highly-conceptual or super math-heavy. A lot of the problems reference material not taught in class and require lots of reading as well as outside research.

Dr. Piatt was always enthusiastic to teach us and clearly loves her job. Although a hard class, she is approachable and easy to ask for help from. Many students associate a class being hard with the professor being bad which is false. Dr. Piatt often provided extra credit and pretty fairly balanced exams with other assignments balancing grades.

What other comments for this class neglect is that this was her first time teaching the course, and she made that clear from the start. It's a hard class, but it's also a 5000-level. Everything was completely fair, and she had plenty of office hours to discuss anything. Some complaints are justified, but she's still a great professor.

When everyone did horrible on the first exam because she changed the format and test material the night (literally less that 12 hours) before she excused everyone of cheating. She also makes things very difficult for no reason (like being able to see the test answers, recitation which turned into a group quiz, and others). Extra credit was nice.

Piatt's class is almost unacceptable for a university, especially as a first year. While taking a chemistry course designed for engineers, you'd expect to be doing a lot of math.

She's a very kind-hearted person. It was her 1st semster teaching, but it was a struggle. There was a big disparity since she emphasized doing all these math-heavy homework/recitation problems but the test was majority conceptual questions and required barely any math. She does offer extra credit opportunities, curves, and tests have less weight.

Attendance is mandatory via daily paper exit tickets. Lectures follow the textbook in order. She says to read ahead, that's unrealistic. Homework and recitation are math-heavy, but tests are fully conceptual and need no calculators. It makes it SO hard to study.

I thought it wouldn't be that bad. It was that bad and worse. If you love and respect yourself PLEASE switch out asap. She assigns a ton of math-heavy homework and then gives tests that are entirely conceptual. Doesn't care how sick you are, you could be blasting out of both ends and still have to come in for the exam. Also her dog is ugly

I'm the first to defend a teacher who has a bad rap, but this is the first time where I physically can't do that. Purposely makes the class more difficult than it has to be, and everyday I hope the T or oncoming traffic takes me out before lecture does.

HOW TO DO WELL WITHOUT BEING A GENIUS: -Actually do readings before class. In-class stuff mirrors exams, so being familiar helps you retain it way better -Exams are super conceptual. Besides weekly HW I did zero practice problems and got an 85 avg on midterms. Slides and reading guides are your best friend. -Get used to being overwhelmed Good luck!

If she weren't a baddie I don't think I'd have the motivation to wake up for class. Midterms only get harder throughout the semester. If you aren't coming to class after already learning the topic, you'll be behind and fail. Homework is entirely math based and is a waste of time when preparing for midterms, which are entirely conceptual.

Many people felt very strongly against Piatt, but I actually really enjoyed the lectures and teaching style. You can tell that Piatt knows a lot about chemistry and is very passionate about it. Tests are difficult but every single one including the final is curved. This class isn't easy, but it wouldn't be engineering without being difficult.

She presents you with the necessary information via lectures and homework, but two things make her and this class suck. One, she will call you out for being on your phone and thinks she is so cool since she went to Harvard. Two, you never know what to expect on the midterms or final. So much different from how the material is taught.

Don't take Dr. Piatt's course if you have a choice. Pretty good lectures and mostly friendly in office hours. Tests were very difficult and conceptual. You might use one of those equations on your notecard, if any. Study by reviewing lectures and reading the textbook. Averages for our first 3 midterms were around 55-60% after scaling.

She uses slides and is not very effective at teaching. Her lectures are given on the assumption that you have completed 1-2 hours of reading beforehand. I didn't use AI for any class besides this one. Homework takes hours and hours and hours to complete, but is of very little use on Exams. DO NOT TAKE THIS CLASS PLEASE PLEASE.
