She's excellent. Her class is not easy, but she is very fair. First-rate lectures. You will not be sleeping through her classes. This is good because that would be the kiss of death in this class.

She is extremely helpful and goofy. Encourages questions and wants to help students learn. Her tests are pretty fair and she teaches everything thoroughly. Holds tons of optional review sessions.

Prof. Dixon is the best orgo chem professor at UMD and told us we didn't even need to read the textbook to pass the class. Her office hours are always open and she is easily approachable. Her exams and Hw are freakishly hard, but you will learn alot. If you have a desire to do well, she will change the way your brain learns the material.

Bonnie Dixon is a really good teacher. If you're taking organic chemistry in order to take the MCAT, DCAT, etc, I would recommend taking her. Her hws are extremely hard and the exams have more material than you have time for but you do learn the material. If you choose one of the "easier" orgo1 professors, good luck in orgo 2.

Orgo I is in itself a very hard class, especially being online and asynchronous. Lectures are thorough and Dr. Dixon is very open and approachable. Definitely go to all TA sessions at least once. My actual TA was terrible but I went to two others discussions and it helped a lot. Homework is hard, so ask questions. They will get you ready for exams.

DO NOT TAKE ANY CLASS WITH DR DIXON! SHE IS THE WORST PROFESSOR I HAVE EVER MET. She expects you to understand super complex ideas that you have never heard of before while she "explains" it at her mile a minute pace. The whole class bombed the midterm and then she blames you for not working hard enough even though you studied 20+ hours that week.

She's a good teacher and very resourceful. She does care about the students and has office hours and study sessions at night (at least for virtual).

Dr Dixon is not a great teacher, the class averages probably ended up being about a-60- 65 and started at about 45-50. Here class was passable with anything above the average on every test, but beware your not getting highschool grades.

Dr. Dixon's homeworks are very difficult and the tests are even more difficult. 100 percent go to office hours whenever possible. GSS is sort of helpful, but their practice questions are a lot easier than the exams. Never miss class and and do as many practice problems as you can.

Avoid CHEM134 with Dixon at all costs. The course is the tests of 135 with no practice or realistic instruction. Dixon basically makes up the lectures on her iPad. She has no interest in being there or teaching the class - something she reminds you of every time you have a lecture. You won't know how to do the homeworks unless you know it already,

Beware that majority of the times she will be pretty rude when going to office hours to ask her questions. But she gives you lots of hw which is excellent practice for exams and a nice grade buffer. She also gives out extra credit so take advantage of that. Try building a relationship with her it will come in handy to understand the unit.

Instead of making the exam shorter, she just gives 10 free points, which doesn't even cover one whole question. The homeworks are also very hard and time consuming.

Dixon is definitely polarizing. She is an experienced professor and is highly knowledgable (she's also quite witty, which makes her lectures fun). However, she's pretty harsh and can make you feel inadequate as a student and frankly, as a person. If you have thick skin and come into the class prepared to work hard, you will learn a ton.
