This profesor knows spanish!! Great conversation starter before you ask those questions in her office hours

Her first exam sucks - the last two and the final are cake, though.

She's a pretty good lecturer, but goes pretty fast. I learned more by printing out the lecture notes and reading them myself than I did from actually going to the lectures.

Exams were fair, as long as you study you will be fine. She is a little impersonable. Does have a lot of office hours however. Lectures were very good, and her demos DID work for our class.

although the material isn't exciting, she does a good job of presenting it clearly. some exams are really hard, although she'll always be there to help

Good at explaining.

I thought Dr.Yerkes does a great job teaching the class... Yes the exams were tough, but this is not high school, it has to be a challenge! She makes lectures interesting by always having demos to get your attention.

she is good

Quite possibly the most helpful teacher I've had in Chemistry. Does an excellent job at explaining material. Exams are a little tough but, hello, you are in college now!

She is really organized when presenting her lectures and knows what she's talking about. Sometimes, it's hard to keep up because she goes fast, but if you keep up on reading, it's pretty easy. She was really nice about helping me with some questions before the exams.

Don't listen to those whiny babies, Dr. Yerkes is a superb professor with organized lecture slides and is available in her office more than any professor I've ever had. Yeah the class is challenging, it's chemistry. If you don't put in, you sure as hell won't get out.

I agree with most comments; she is very, very tricky/difficult, but she is also very knowledgeable, friendly, and helpful. She's a very effective teacher, but I really don't think her exams are completely fair.

Excellent teacher. Course material is not impossible, but it's fast-paced (keep up with the work, an A is doable). Furthermore, she is extremely helpful: she welcomes students even during non-office hours, holds review sessions before each exam, etc. Also very sympathetic to personal probs - lenient conflict quiz/exam policy. Nice lady.

She is a very nice person and a pretty good teacher. Yes, I felt that she made very hard and unfair tests, but she did made the effort in giving the students as much help as possible. She is also very nice about giving lots a points away through homeowrk and quizzes. The least you should get is a C!

I had her for both classes and got in A in both also. She'll help you if you just ask. Good prof!

Very clear and concise.

Powerpoint slides are cluttered, but she ties in chemistry into real life. Demos are horrible though

her lectures are okay..she uses powerpoint whihc I am not a big fan of when it comes to teaching chemistry. Her tests are hard, you need to pay attention to the tiniest detail.. she is very willing to help outside of lecture...she's available for help almost anytime. Overall, she's okay..it depends on your choice

A very good Chem prof. The class is well paced so that you don't waste time, but you don't go too fast and you end up getting a lot done. Exams are very fair in 102 and slightly more difficult in 104. She always clear in what she expects and explains material very well.

She is one of the best professors I have ever had. Her presentation is well prepared and she knows what she is talking about. She is always very welcoming and professional at office hours. You have to work for an A, but that's any chem class.

Very good lectures. Very smart. Very welcoming. Office hours all day essentially. Hard to get an A, though. Tests are difficult.

She is very clear and her tests are hard, but fair.

Overall, I really enjoyed taking the class from her. She used powerpoints which got cluttered at times, but if you pay attention during class, you can sort them out. She was ALWAYS available in her office and was always very welcoming and helpful. Exams were very difficult, but combined with quiz grades, an A is very possible.

She's really good. Her test are difficult and you really need to study if you desire a good grade. She is very helful, though a bit unclear at times.

Very very hard tests. Lectures move at a thousand feet per second. A tough class but shouldn't be hard to get a solid B.

At first i went to lecture, then i realized it was pointless because all of her notes and powerpoint slides are online. her lectures were alright, but kind of boring. I got an A in the class and thought the tests were really easy if you study for them. She was a decent professor, but again i didnt go to all that many lectures.

Yeah for Dr. Yerkes! She was a wonderful professor, and very caring for her students. If you ever need help, she is always happy to help during her office hours. I loved the class, and I found her power points very effective and helpful. I would highly advise taking her for CHEM 102/104! Much better than hummel!

Amazing professor. One of the best lecturers I've had! Go to office hours because she can explain everything soooo well.

She was an excellent professor. She went really fast in lecture but if you wrote down questions and went to office hours she would explain the questions perfectly. She's great. Really caring and she remembers names which is a plus!

She talks really fast and moves through the material pretty quickly but if you go to office hours she'll go over everything again

talks fast so pay attention

The thermodynamic part of the class was easily the most difficult section. The class wasn't that bad, but she wasn't very good at lecturing. Things would be on the exams that she barely touched on in lecture.

Yerkes is GREAT! Print out the powerpoints BEFORE class, and just take notes on those. and GO to office hours! she was amazing and even helped me on a chem lab she knew nothing about. She's so nice so don't be scared! it's a HARD class on its own but i pulled off an A-

Great professor, if you are at all competent you shouldn't get less than an A.

Make people sleep

She is a decent professor. She definitely should not read straight off her powerpoints like she does, and her tests are tricky for no reason, but if you can pay attention and keep up in class, you should do fine. One thing that really helped me was getting the book of past hour exams from the bookstore. If you can nail those, you will be fine.

I took yerkes for both 102 and 104...no its not an easy class, but she is the easiest of the chem professors i think.If your a more math based student shes a better teacher for you.she stresses math above conceptual stuff.need help, go to her office hours, shes cool and down to earth. for chem 104 i barley went and got a B+.Not too hard of a class

Not a bad professor, in my opinion. Her lectures are streamlined and very easy to follow. She does stress basics during lecture, but she gives plenty of opportunity to apply all the course material before exams.

Even though I hear a lot of people complain about Yerkes, I really didn't think she was all that bad. This class is in no way easy but as long as you go to lecture and pay attention you should do just fine. She does fly through lecture pretty quickly so make sure to keep up. Her quizzes are easy but watch out for her exams, they are no joke.

Yerkes is an awesome professor. She is always available for office hours and is really helpful. She posts notes, lectures, practice problems, and many other resources online, which a lot of other professors don't do. As long as you try, you should be able to do just fine.

Prof Yerkes knows what she's talking about and even though she does speak fast during lectures, she is ALWAYS available for office hours to clear things up. She is pretty straightforward and is also really flexible when it comes to grading. She is also better at preparing you for organic chemistry than some of the other professors.

She was fabulous! Honestly, I don't understand why people rate her below 5 stars. I'm not terribly amazing at chemistry but she helped so much during her office hours. I advise everyone to take advantage of that. She's very understanding and she is honestly THE BEST professor I've had here. Props to Yerkes! Review the Lon capa for the quizzes. It really helps to get those done early.

For those of you who hated 102 with Hummel, never fear, Yerkes is here! She was a GREAT professor who made me actually like chemistry again after the disaster that was Chem 102. Go to her office hours if you don't understand something and be thankful for the pre-orgo stuff she teaches you, you'll need it later! :)

very helpful and nice!

Her tests are much more manageable than the other sections.

if you do the homework and go to discussions you're set!

Incredibly helpful, she's in her office for a good portion of the day and tells you to come by if you need help. Presents the material in a good way. Challenging tests, but fair.

As nice and helpful as dr. yerkes appears, i couldn't help but to doze off in her class. She speaks the entire time and, although she has good intentions, her low-sounding voice can make anyone fall asleep. Hw is understandable, quizzes are okay, but exams...they are something else. They contain material that you've never worked with before.

people complain about her way too much. pay attention in lecture. she knows her stuff and gets it across in a good way. tests are fair and the mock exams she puts up are very similar to the actual exams. it's a hard class for a reason.

Yerkes is a professor who knows what she is teaching, but sometimes goes too far in depth (for 102). The exams were typically similar to the practice exams, but often the questions were tricky. Several times there were wrong answers on the keys for exams, but upon confronting her she would give me points back. Good if you know have prior knowledge

Her class is, and test are very hard. But she is very nice, smart and willing to help you. Pay attention in class and do the homework and quizzes to help study. Exams are usually curved pretty well.

Great woman. Clearly knows what she is teaching and hands out plenty of practice. Also has power points which are helpful to study off of. Always willing to help as well.
