shes a little loppy.. but a good prof. she doesnt teach as much as the other profs, which makes you feel like you aren't learning what you need to. ive tried asking her questions after class and she just doesnt understand what im asking and gives unclear answers. read, go to class and discussion, study and you will be fine.

I have mixed feeling about the class. I thought she was a good professor but she often came in unclear.

Alice has the best intentions, sure, but she makes it obvious that she does not know what she is doing.

Chemistry does not come naturally to me, so it would've taken a fantastic professor for me to learn, and unfortunately that was not Professor Mignerey. She teaches like her students already know the material, and her tests ask challenging questions that she hadn't previously shown making them hard to prepare for, but she does have a lenient curve.

Easily the most pathetic professor in the UMD Chemistry Department. Although she is no doubt a smart person, her inability to teach basic chemistry was extremely frustrating.

CHEM135 is one of the hardest intro classes at UMD, especially if you have little to no background in Chemistry. She goes through PowerPoints and examples in class (albeit quickly) which I found helpful and she is eager to answer questions you have. Nevertheless, studying is a must and I highly recommend her office hours, especially before a test.

People give her a bad rep because chemistry as a topic is hard to learn quickly. She may not be the best at explaining things, but she shouldn't need to if people are ahead on the reading. If you read ahead and do the homework well or at least try, you'll be fine. I can't emphasize this more, STUDY FROM THE CHEM101, the exams are made from it.

Professor Mignerey is a terrible teacher. She has a tendency to simply put things on the board without any proper explanation as to the steps or the logic behind the problem. Additionally, she is very rude. She has no respect for students, your answer could be correct, but off by a decimal, and the complete answer will be marked wrong.

Honestly, Professor Mignerey is mean. Countless people would ask questions in class and she would laugh at them or give an extremely condescending response. The class has so few grades so it makes it very difficult to get an A and the final seemed way harder than any of the problems we did before. Don't take her

If you test with ADS, I recommend you don't take her class. She grades ADS tests last so I got mine back days after the rest of lecture and was unable to view my final since it was not ready at the same time as non-ADS tests. Overall not an awful lecturer, but incredibly rude and uncaring. I had to study for 10 hours each exam to get an A-.

Dr. Mignerey is very smart but she often skips steps, goes too fast, and covers too much content, making lectures very confusing. We had 4 midterms, a final, daily pop quizzes, and an absurd amount of homework (hours every day). Her tests are difficult and each one averaged a C or D. She does offer a generous curve at the end though.

Professor Mignerey accused me of being a liar when I asked her about inconsistent grading on her test, when a classmate received credit for the same work that I did, when I had not. She is rarely available, pretty rude, and practice assignments do not correlate with the tests provided. Rely on Organic Chemistry Tutor on YouTube for learning this.

She is terrible at explaining the actual concept she's teaching. During her lectures, all she does is example problems. That is how she teaches and you will be expected to understand every step she is doing. One good thing about her is that she pushes due dates back for homework if you email her ahead of time. Get ready for stress if you take her.

DO NOT TAKE W/ MIGNEREY. IF YOU ACTUALLY WANT TO LEARN AND UNDERSTAND TAKE SOMEONE ELSE. MIGNEREY is very rude and highly unapproachable. During lectures, if you ask a question she gets an attitude and responds with im not gonna ask you that. Exams are mostly mathematics.

THE WORST PROFESSOR."Teaches" high level physics rather than general chem. Teaches is in quotes bc she really just does practice problems and expects you to understand. Then if you ask her a question, she is super rude and condescending and will laugh at you. Save your time, pick a diff professor.

The saving grace for this class (Radiochem) is that the topic is her specialty so she was comfortable sharing her life's work. There were a few homeworks that she would take weeks to grade. However, ALL exams (including the final) were take home and not timed. She even bumped students grades after all was entered. Can't use a pc to save her life.

I would say avoid this prof at all cost (especially if you're that great at chem). The class itself is pretty difficult and the class average in the class is extremely low. The only reason why I would recommend her is because of the gracious curve at the end of the semester which for me was roughly 30%. The TA, Sam, is amazing tho.

They give you online hw (~ $30-80 dollars) and every week you get 144 questions and more if you get them wrong . It takes me a WHOLE DAY ( 7am to 7pm) to finish. Don't go to lectures she doesn't teach use YT and have gpt 4 explain the slides. I could've saved 240 hours (Literally 12*16weeks =192 + (1 hour to dissect each lecture *3) *16=48 )

Professor Mignerey's lectures rarely *explain* new concepts when they are introduced, so if you want to really understand anything, your best bet is to teach it to yourself before lecture. Test averages were consistently low, and the tests were usually harder than the review material. Don't take this professor if you can help it.

Just a heads up for those taking CHEM135. Take Griffith or wait till another semester. Never take this woman at all COST. She is the worst UMD chem professor I ever had. Took Griffith after her and pass calmly since she relates it to engineering. Mignerey is just doing hardcore general chemistry with extra unnecessary work.

She could barely read off the slides. The discussions were useless. The test prep was useless. The class got curved at 45% to pass because she is such a bad teacher. Genuinely such a terrible experience in her class. There are little to no resources available. Go for Griffith, I haven't heard one complaint about her.

This woman is easily the worst professor on campus and don't know why she isn't yet fired. Her lectures make 0 sense because she does examples & more than half the time makes mistakes in them too. She spends atleast 20 mins of the class trying to figure out how to use the technology. Her exams are poorly worded and homeworks take 15+ hours.

She's not a mean or bad person, just a horrible teacher. She covers roughly 30 to 40 pages of textbook content in a singe 50 minute class, and explains things in the most confusing way possible. Every single person I know who took this class spent upwards of 3 hours a day just studying the textbook to make up for her horrible teaching.
