Dr. Duis is great! She inspired me to pursue chemistry as a major. The class can move kind of quickly and the test are not easy, but study like crazy with all the material she provides and you will do fine.

This class is easy as long as you try to understand the material. There are weekly quizzes and she gives lots of clicker questions which count as points with her power points. She drops one quiz at the end of the semester. She is very helpful and responds back to e-mails very quickly. There is a lot of Mastering Chem. homework though.

Dr. Duis is an amazing professor that makes learning chemistry easy. She offers lots of extra study materials online and is nearly always available in her office or by email for questions. Although she is not necessarily an easy professor, she provides plenty of opportunities for students to practice the material and generously curves the exams.

If you actually watch the pre-lectures you will be fine. Don't just take notes off of it or you'll be lost. The recitation for the class is super helpful espically if you want to learn how to do harder problems than she gives in class.

Duis is a great professor. Her class is super organized and she gives you a lot of practice to make sure you're actually learning how to do chemistry instead of just regurgitation. She isn't the best professor and has a monotone voice, but if you pay attention in lecture you'll get through it.

Hard professor and very monotone voice but there for you if you need help. Recitation and SI Sessions are super helpful. Not an easy class. A lot of self teaching you have to watch every pre-lecture video in order to understand what is going on.

She's is a wonderful teacher. But she may seem quite intimidating at first but during her recitations she is the sweetest professor you'll find on campus. She sincerely wants you to pass and if you study and work for it, you'll get that A! She also averages the individual and group tests which is AMAZING :)

There are pre-lecture notes, COPY THEM. She gives out short quizzes in the beginning of each lecture. DO YOUR HOMEWORK. They're actually not that bad! Her exams are only hard if you didn't study. She answers anything and everything so clearly! Amazing at lectures, funny/sarcastic, she really wants you to pass! Take the recitation too. Work for it.

Her exams are pretty short (17-20 questions). She always gives out a few extra credit points on the text, Look out for them! Do the homework and always ask for help. She'll make chemistry easier to understand. She's great at explaining things.

Professor Duis is a great teacher. Hands down my favorite. The class is fairly easy if you have taken chemistry in high school, basically review. She's really funny and makes the lessons interesting. I definitely recommend taking her if you can. I know she will be teaching Organic Chemistry soon!

As someone who personally barely made through basic Chemistry in high school, Dr. Duis made everything very understandable for me and responded to my emails within hours. If you don't go to class it is really easy to get behind because she does move fast. While attendance isn't mandatory, there are clicker quizzes and questions everyday for points.

Duis is a great teacher. Occasionally hilarious. I really jived with her teaching style, she is super straight forward and really knows how to get to the point because there is a lot of material to cover in 151. I took AP chem in high school so I had a good background in chemistry, but I've never understood chemistry as much as I did in her class.

Wonderful professor. She cares about success of students, will work with you to help. Lectures are ppts with mostly practice problems. Very hard content but she will answer all questions you have. Very down to earth, understanding. Never opened textbook. Attendance graded by iClicker Q's. Gives a few extra credit opportunities. Would take again!!

Dr. Duis is the most humble person you will ever meet. She is extremely helpful in office hours and takes the time to make sure you understand the material. I have had her for 152 and 235 and she is amazing at teaching all levels of chemistry. Read the required material beforehand and lecture will be seamless. A diamond in the rough of chemistry.

Insanely hard class. Duis does a great job at making things understandable. Be ready to STUDY. I recommend enrolling in recitation, the more you practice the better. Need to attend every class to stay on top of content, attendance is iclicker questions for participation points. Tests are brutal but fair. Textbook required but I never used it.

Dr Duis is an amazing professor! Organic Chemistry is an incredibly difficult subject to teach, but she did a fantastic job explaining everything. Go to office hours if you are in need of extra help.

Prof Duis is a great teacher. She's quick and to the point about the concepts and understands that it is difficult material. I would recommend if you are feeling scared about taking Organic Chemistry because I was extremely intimidated and now I feel confident enough to actually like it. Also, she relates to students by cracking jokes. 10/10

Dr Duis is an exceptional professor. She goes above and beyond, grading things almost immediately and was always available for extra help. She is incredibly compassionate and sets the standard for what makes a great professor. Overall, she does a fantastic job! We loved being in her class. :)

Dr. Duis is very kind and she makes jokes during her lectures! She is a cool professor who is a bit shy but knows what she is doing. I would definitely take her again if I could! Go to her office hours, she is so nice!

I had professor Duis for 152 and O-Chem. She is by far the kindest and my most favorite professor at NAU. She does not pressure her students and is very willing to help during her office hours which makes for better learning. The class is difficult but if you put in an effort (SI, office hours, recitation) you will get a good grade.

I loved being in Dr. Duis's chem 151 class. Make sure you do the pre-lectures because she has pre-lecture quizzes that are small points but add up throughout the semester. Her exams were difficult but the group exams bump your grade! Do the extra credit she gives at the end of the semester. I had an A all semester until the final.

Ochem is very hard and that's why people don't give Dr. Duis good ratings, but I really enjoyed her class. She's shown numerous times that she cares about us, especially in the terrible situation we are in right now. Yes, her exams are very hard, but they are doable as long as you practice. There's also a lot of partial credit! Highly recommend!

Dr. Duis is a wonderful professor! I was very nervous about taking ochem, but ended up doing really well in her class. She genuinely cares about her students succeeding in this course. Sign up for recitation too. Do not be afraid to ask her questions, she is understanding and cares. Take her for ochem and it you will do well!

Dr. Duis cares about her students and wants everyone to succeed but you have to be willing to ask lots of questions to make sure you're understanding the material. Her lectures can be a bit boring and there is clicker questions every lecture. The practice exams are the exact same format as the real exam. This course is definitely hard but doable!

Dr. Duis is always willing to help you if you make an effort to reach out to her. She is very understanding and had extended deadlines and let students retake some quizzes before. Only downside of the class was that you do a majority of the readings and pre lecture questions before Duis teaches the material. So its up to you to learn on your own.

Dr. Duis is an amazing professor. If you really want to get an A, there are so many resources available to get there. There were at least 2 practice exams available before every exam. She is very quick with emailing and always willing to help. People complain that she goes fast, but that's just because there is so much content to be covered. 10/10!

I had to retake this course and in comparison to my last professor, she was a gift sent from God. She made the material way more understandable for me and I would have received an A but I skipped out on A LOT of zoom calls, so make sure to attend her class. She is available through email always and helps out always when she can!! Highly recommend.

I did not do well on the first exam, but was able to change the way I studied and ended with a solid grade. I recommend reading Organic Chemistry as a Second Language after class to understand the reasoning behind everything. You will have to work, but it is possible to do well in this class.

Dr Duis can seem intimidating at first, but she is very willing to make accommodations when you email her. She lectures decently quickly, but there is a lot of material to cover. There's a decent amount of homework. There are clicker questions.

She tries to make the material understandable but has to go quick to ensure we cover all of the topics. Ochem is hard, outside studying is helpful to doing good in the course. She uses iclicker reef for attendance and participation, which you have to buy. She has powerpoint lectures with PDF available to follow along without writing everything out.

Dr. Duis is very caring, and is very easy to work with. The class has difficult content so it is difficult, and her tests are difficult, but if you use your resources and work hard you can do well in the class.

She lets you know exactly what to expect at the beginning of the semester. She's also extremely chill, understanding, and willing to work with you. Her whole personality is just amazing.

Dr. Duis was really great. She explains things very well. I would highly suggest reading the assigned reading before class, as everything will make more sense. Overall Dr. Duis is a very solid choice when choosing a chem teacher.

As long as you read the material and do the homework the class is not bad. She does a group exam that really helps bump up your grade for every single test. She responds to emails super fast and gives extra credit. She wants her students to succeed and gives them the opportunity to.

If you do the homework and pay attention in class you should do fine. She cares about her students and is funny during lectures. Most of the class is practice problems. There are alot of opportunities to get points. The tests are taken individually then as a group. I recommend taking Dr. Duis for chm. Chm is tough but she makes it a bit easier.

Honestly, this was the hardest class I took last semester. I went her office hours every exam and I am so thankful for this woman. At the end of the class I had a 88.6 she reviewed my final exam with me and I told her getting an A meant a lot to me the achieve extra credit and class extra credit plus her little curve was enough to make the grade.

She is a great professor, very understanding if you miss assignments or anything. You will probably have to teach yourself a little but that is with any Chem class.

Dr. Duis is great! She provides so so many resources -- including practice worksheets, note worksheets, and tests from previous semesters to help you study and prepare. Organic chemistry is going to be a difficult class no matter what but Dr. Duis ensures the resources to help you succeed are available. Dr. Duis genuinely cares about her students!

Jennifer Duis' class was very informative, but also incredibly challenging. The amount of homework assigned sometimes felt like a tsunami, but the lectures and Google help to pad it out. She likes to use iClicker questions, so have your phone handy. She was also always willing to answer questions students had about the materials.

Great professor and very easy to talk to and seems like she really cares. Can take exams with your group to boost the grade as-well.

Dr. Duis is exceptional. Extremely caring and competent, and while this was a very difficult class there is no one else I would rather take it from. She is very kind and fun and keeps what could be incredibly dry material as interesting as possible, and she is all in all just phenomenal at her job. She gives participation points on tests even, lol.

The teacher was very passionate in making sure students that needed help on the topics received help. Tests are hard but there is a group portion that helps your grades. Recitation is helpful if you come with questions, but otherwise the worksheets are all online. Class is entirely lectures. Going to SI was very helpful for this class as well.

Relies on students reading the textbook before class and can be difficult because of unlearned material + grading. Luckily if you have questions she is always eager to help and responds to emails quickly. It is a difficult class, but it is obvious she wants the students to succeed. Definitely requires lots of studying.

Professor Duis is the best teacher to learn from in the chemistry department. She helps you learn and understand the hard material and the exams are a certain amount of time by yourself than with your group and she averages the two grades. Professor Duis really cares about her students and wants them to succeed

There is a lot of homework, but she is an amazing teacher and really helps make these difficult classes easier. Reach out for help sooner than later. Take advantage of extra credit she gives out. Make sure to read the textbook, not all of it is covered in class.

Duis is really kind and explains lectures very well. Would highly recommend attending recitation and SI alongside her lecture to really understand everything. Duis is very understanding and is able to accommodate students if needed.

Chem235 is a tough course, no doubt. Dr Duis makes sure you know what is going on and actually teaches to make things seem much more simple than they are. She is very encouraging and gives you many chances to get things right.

I love Dr. Duis. She broke down the content so much. Ochem is hard; it always will be. Buy ochem as a second language and read alongside homework and lectures. Use the practice exams; they're identical to the exams. Crazy extra credit on exams if you know all the content. If I actually studied properly, I could have gotten an A.

Dr. Duis is a fabulous teacher. This class is one of the hardest classes I have ever taken, but she made it understandable and manageable. If you are taking this class be prepared to work your butt off. You need to go to every class and utilize SI opportunities for this class. If you put in the effort it will pay off with this class and teacher.

I love Dr. Duis! I have a really hard time with chemistry, I studied very hard to pass. Shes the best CHM professor, Ive had the others and failed. Dr. Duis explains well and cares a lot about students. Practice exams were identical to real exams. The final was not created by her but she gave so much to study from. Thank you for a great semester!

Best professor ever. I got an 89.2% and she rounded it to an A. Class is super difficult but the lectures are awesome. She answers emails daily and welcomes questions. 12/10 would highly recommend.

I cannot stress enough how excellent she is as an educator. She displays authentic compassion and interest in her student's success and encourages them to strive for excellence. Do your part as a student and you'll do just fine. Tip: watch her lecture videos and DO the practice exams and worksheets she posts.

Really caring and knows a lot about the subject. Tests can be taken in groups for more credit.

Dr. Duis is amazing for gen chem. She provides so many resources for students to be successful and makes it known that the class will be difficult from the get go. Any low reviews are from people who just don't study and put in the work. She's very accommodating and so sweet, open to answering any questions. Will definitely be taking her for ochem.

This is a very difficult class but Duis is a good professor. Good luck.

Gave group tests with extra credit opportunities, great lecturer

Dr. Duis was awesome! She is quick to answer emails. I highly recommend signing up for recitation. Study all of the practice exams she gives, as it is an extremely good reflection of her tests. Homework a manageable and isn't busy work. For tests, you have 40 mins for your test and 20 for the group test, which can only help your grade (love it!!).

Chem 151 is generally a hard class, but Dr.Duis makes it as easy as possible. She gives out extra credit assignments and extra credit on almost every test. We took our tests individually and then as a group so our scores would be raised no matter what. She's definitely the best chem professor. Has office hours, SI sessions, TAs, and a recitation.

Dr. Duis is wonderful, she really cares about her students and wants you to succeed. She's more than willing to provide you with any help if you just ask. Her lectures are integrated with participation questions that actually help you learn and practice the material while getting help and feedback on the topic. Absolutely take her for 235!!!

Very accomodating and knows how to explain concepts well. if you dont understand something she can most likely re-explain it in a way that makes sense. Made taking her class at 8am worth it.

Really good teacher, especially for a class like O Chem. The class itself is so hard, but she is a really good teacher and it's clear she cares. She will sit and work with you through a problem, super sweet.

Good professor

Dr. Duis is great for gen chem 1, but keep in mind there is a lot of homework for this class. Before class there's easy and short prelecture quizzes, one quiz and one homework assignment per week. You also take exams as a group and individually. She's super nice, even though she seems intimidating, and is always willing to answer questions.

Great professor. Really enjoyed lectures and she was very helpful with any questions.

Her lectures were a little hard to follow sometimes, but going to SI sessions and her recitation helped me a lot. Also ALWAYS do the extra credit, I had a high B and she ended up changing my grade to an A. The practice exams also help a lot in preparing for exams, and you get to do the exam with a group to raise your grade!

Dr. Duis was amazing instructor. She works so hard to make sure her students succeed and is such a kid person. Her class is very homework heavy and tests are hard. She helped me pass her class when I was really struggling. She also has plenty of outlets for you to practice chemistry such as recitations, tutoring, and SI.

I absolutely loved Dr. Duis! There was a lot of homework but it was a 4 credit class so that makes sense. She was very responsive to emails which was very appreciated and overall helpful. There is 1 quiz a week, taken online, but if you need any help, you can email her and ask questions and she is very sweet. I will be taking her again :)

Duis is an accommodating professor who explains concepts clearly. Attendance is mandatory, but the extra credit opportunities and group exams help offset the difficulty. Unstuck ai was a lifesaver for preparing for tests.

This course itself is pretty hard, but professor Duis makes it manageable. There's no way you don't pass if you study. She gives you SO many materials to study like past exams and worksheets. She responds to my super late emails and always helps. Honestly, if you fail her class then you don't study enough or don't show up to her lectures.

Dr. Duis has been a great teacher. Class material is hard but if you do the homework and go to class you'll understand it for the most part. If you are between Duis and another professor choose her you wont regret it.

Dr. Duis is an amazing teacher. O-Chem is a tough class, but she's the best. Her grading criteria are clear, she is there to help, and she gives old tests for practice before exams, so you know what you're getting into. I recommend her recitation class since it is one-on-one time with her for help. She can go fast, and slides can be wordy, though.

Lots of pre-lecture assignments every week, but they are generally easy and quick to finish. Homework pretty much every week, as well as weekly quizzes and 4? in person exams. Lectures can be boring but are based on slides which are available for download in canvas.

Ochem was such a hard class in general and I hated it. The tests are the main part of the grade and the tests are so hard. But Duis made it tolerable and helped me to pass at the end of the semester. Amazing professor.

Incredibly helpful, always makes a point to check for questions. She's funny, passionate about chemistry, and has helpful class structure. If you take her class, study before the lecture. It helped me a ton to get a baseline understanding from the textbook, then expand on it in class.

Her lectures are not the best, but she always tries to make sure you understand the material if you ask questions. She is super caring and approachable, and the workload isn't too bad. Ochem is hard no matter what, so you have to study a lot outside of class. I would take her again. She curved the final exam for everyone.
