She is awful. The tests are not given during class time so you have to make yourself available for whenever works for her. She gives polls during class that count towards your grade but its on information she has not taught yet and she doesn't give you a warning for when she is closing the question. Legit just don't take her class, she's the worst.

Please do not take this professor for CHEM335. It is so obvious she has no idea what she's doing. She doesn't teach, she just reads off slides. The class schedule is an absolute joke. Unless you NEED to take this class, I would highly recommend against it. One of the worst professors I've ever had.

Probably the worst professor I have ever come across at Bing. She just lectures like she is recording a Panopto video, she does not stop and ask if anyone has any questions (almost everyone is lost). She will give timed polls with NO warning of when she is ending it (and they count)! No clear grading criteria for participation or self-assessments.

The lab portion itself is fine, and should be the only portion of this class in my opinion. The lectures are useless, not applicable to the lab itself. Participation points are so unclear, tests are hard. Would probably do so much better in the class if there wasn't a lecture component. Supposed to be orgo LAB but is treated like orgo class itself

Dr. Karugu is a wonderful professor but the 335 course is downright miserable. It is unnecessarily stressful and done in poor fashion in my eyes.

When registering for classes treat orgo lab as a 4 credit course.

Very nice, just isn't a good lecturer. I had a hard time understanding everything in this class. I dropped the course; it was overwhelming as this was one of four courses. I had to learn nearly everything myself. It's even worse seeing I (would've) had to go to ten labs for ZERO lab credit. It's a waste of time, don't do it. Just go into 104.

Professor Karugu is a nice lady but her lectures are irrelevant to the exams and discussion quizzes. I had to ask my friend who takes chem at a different school, for their notes. If you are planning to be a nursing major, take chem 104 or take it somewhere else because it is not worth your time. If you have a good TA, labs will help your grade.

Karugu is a nice lady, however, I did not learn well from her teaching methods, I could have learned Chem 101 better from youtube. She makes concepts more difficult than they are and moves super fast. However, I do appreciate final grades are not only based on exams because I would have failed if we did not get so many points from homework and lab.

Prepare to teach yourself the course. She is nice but isn't very good at lecturing & only reads off the slides. She explains everything in a way that can make easy stuff confusing so you have to teach yourself an easier way. She does problems in class but never finds the answer herself to confirm the students answer then won't put it on the board.

Professor Karugu seems like a kind person but is not enjoyable as a professor. She kept cutting times for weekly quizzes and was not receptive to students struggling. There is a lot of self-studying required because she makes everything overcomplicated. Luckily homework assignments are easy points, but many exams were in need of a curve, and/or EC.

Honestly I think these ratings are a bit harsh. I got an A and that was with getting a 60 something on my last exam. Show up to lab and lecture, do the work and you'll be fine. Spectroscopy at the end of the semester sucks so leave yourself room to do bad on the last two labs and last exam to get a good grade.

Dr. Karugu can come off as abrasive and at times could come off as mean, but I don't think she intends it this way. She is very smart and very enthusiastic about the course. The class is significantly more work than it should be but all-in-all it's a very easy class that takes very little effort

Dr. Karugu was knowledgable in the subject of organic chemistry lab. The workload for the course was somewhat light, with only two lab reports (one having a regrade) and three exams (no final exam). The lecture material emulated the questions on the exams very closely. Randomly, she accused us of stealing her exams from her on multiple occasions.

CHEM 102. The 2nd semester of this sequence was much better than 101. She began giving EC and the exams got slightly easier. However, she still can be unclear in lecture which leads to mass confusion. Nice as an individual though.

Dr. Karugu is more than qualified to be the lab coordinator for Orgo lab. She isn't mean she just doesn't put up with nonsense. She is very accommodating and caring. Show her respect and she will return it and make your life easy. Don't let the bad reviews scare you, she's really not bad at all and your lab TAs are on your side too.

this class is low key light work so i really don't understand why everyone hates her. just do your work on time and pay attention in lecture. she's a decent lecturer and is very clear about her expectations. yes, it's a stupid amount of work for a 2 credit class, but it's really just busy work. show her respect and she will show it back to you.

This a 2 credit with the work level of a 4 credit class. She is also so disrespectful and rude to students. The first day of class she yelled at someone for being late and make them walk all the way to front of the room to sit right in front of her. Just do not take this lab unless absolutely necessary. Not worth it at all.

As Chem335's instructor, it should be her duty to get the teaching assistants ready to train the students. But at the TA meeting, she yells at everyone for 70% of the time. anytime someone asks a question. To keep students from ever asking her questions, she taunts them! She is to blame for the psychological stress of the TAs and students!

Anyone complaining about this class doesn't know how to properly balance their time. Imo there shouldn't be lecture exams, but they're carbon copies of the practice questions and if you just reread the lecture slides and do the example problems from them, you'll be fine. Lab section is dependent on your TA, not Karugu,& her expectations are clear.

I never saw any of the rude/crazy behavior ppl have commented before, so speaking on her as a person, I found her to be pretty chill. I don't agree with having 3 exams, however, they weren't too difficult and based on the practice exams. TA is most important. I had Obaje and he was a chill guy but didnt agree with his grading.

As a chem major, chem 335 is honestly the lightest upper-level chem lab. There are only two lab reports, and each pre-lab doesn't take more than an hour. There are exams that are a little tough, though, and a lecture component. A B+ to an A is very achievable. Dr. Karugu is very strict, though. Expect no extra credit and no showing up late to lab.

Really strict about attendance for the lab. She's unnecessarily rude and has a power trip. My friend used the bathroom for 2 seconds while the TA waited for him to start the safety protocol. But she wasn't okay with that, so she kicked him out and told him to go home. Now he has to do a makeup lab and wake up at 7:30 in the morning again.

This professor is just kinda rude. 2 kids in my class went to the bathroom and she wouldn't let them back into the room. This was at 8:02ish before the slides begun. Kinda crazy to not let someone pee. the 1 kid got kicked on the day it was a 4 person lab. I asked if we could then join other groups she said no. the CAs are awful to study for.

I don't know how she got this position, but she sure isn't here to help anyone! She has so many poor reviews, and its not hard to see why. She kicked out students for using the bathroom during a 4-hour lab, even though they received the TAs approval first. The TAs do all the teaching, and it's clear they're the ones actually making an effort.

She is rude/condescending when asking questions and unfair in grading. 3 lecture exams and 2 lab reports with weekly prelabs make it a 4-credit level coursework when it is 2. She won't even let students return to the lab after using the bathroom, even with permission from the TA. The TA's do all the work, and she is rude to them as well.

Tests are a waste of time but other than that I didnt have a problem with her. I never saw the rudeness people complain about. Lectures were pretty good and prepared me for lab every week. The lab reports really aren't that bad if you are good at managing your time. NMR at the end of the semester sucks but other than that the class is pretty easy.

Tbh she was pretty sweet and responsive to questions. Her lectures were straightforward and helped on the tests. The only annoying part was for the last exam we didn't have many lectures (due to breaks/tests) to explain the background of techniques, so we has to self-study from the manual. Heard she's very strict with being on time for lab though.

this class was not as bad as everyone made it seem, the lectures are actually helpful for completing the labs and if she talks about concepts or says statements that are not on the slides write them down because she may include them on exams; there are two 15-20 page lab reports but they weren't that bad; genuinely enjoyed the labs

This class is very challenging since the tests cover organic chemistry concepts and lab material, and the grading for labs and reports is strict. Dr. Karugu is patient and always available to help outside of class, which I appreciated. I just didn't enjoy the four-hour labs or the CAs (assessments in class).

Lecs ok- covers lab concepts & attendance taken. 3 lecture exams quite hard & based on lab concepts (no drop). Lab is a lot of work, sometimes too much- stayed full 4 hrs for most. TAs pretty strict. 11 labs & lowest grade drops- these boosted my grade. Post-lab done in lab- come prepared. No xtra crdt. Prof herself is receptive & understanding.
