Incredible teacher. He gives very clear, creative lectures and has a great sense of humor. His tests are challenging, but make you feel like you've accomplished something.

Good teacher. Explains things well and uses Powerpoint slides that you can download off of his site. He's very passionate about chemistry and teaching it and watching him do demos is like watching an excited child - pretty funny stuff. After Lawrence, any teacher is good though.

He's an excellent teacher! I've learned so much in his class, better than the last chemistry class. He has a clear understanding and passion for chemistry and the lectures are somewhat based on the book so if you don't understand something, you can just refer back to it. The online homeworks are helpful and the YouTube links are great!

He is bright, funny, and down-to-earth. He is a young professor so he is still interested in teaching (versus just doing research). His door is always open. If you go to lectures and do the homework, you will do well (The questions on the final were ALL from previous assignments). A good person overall.

I really enjoy him as my Professor. Chemistry is a pretty tough subject and his tests can be a little tough. I have talked to a lot of people and he is the best. Get to use a note sheet on tests too!

He's alright, he is a poor test writer, makes mistakes. Really sucks when you're taking a test. Just copies notes/slides from the book. Cool Professor though, lots of discussion on WebCT and *gasp* he knows how to use technology.

Overall a pretty good prof. Sometimes it seemed like he doubted his logic when challenged by students. Very useful WebVista!!!

Great professor, very helpful and clear. You will learn chemistry with this guy.

Pretty Amazing Prof. His lectures are quite cerebral.

very smart dude who really likes what hes doing. lectures can blow your mind sometimes. strong emphasis on application of science. test really test your understanding

Great professor! I hate chemistry, but I actually enjoy Massari's lectures, which is saying something. He is really funny and does a lot of demonstrations, which keeps class interesting. Tests are hard, but the class is curved so if you work hard, you can get a good grade.

I think Professor Massari is great. He makes lectures fun, and provides you with a lot of real-world applications. His tests are fair but challenging, and there is a curve. You have to study for this class, as you do for any chemistry class, but you learn a LOT if you put the effort in! He is funny and really helpful whenever I ask questions.

One of the best teachers I have. Even if Chem isn't your thing, he makes it fun and understandable. Lab is tough, so are tests. This isn't an easy class, but you can definitely get a good grade. Overall, FANTASTIC TEACHER! :)

The averages on his midterms tend to be low- they're tough! But the curve is very generous. Lots of feedback on webvista, he tries really hard to give everyone the tools to do well- homework, practice exams, time trials, etc.

General Chemistry courses aren't all that exciting - at least in my eyes. However, Professor Massari was fun! He made me laugh a lot and most of the time his lectures were clear. He also tried to help as much as possible and was genuine - he really wanted you to do well. His exams were tough, but like I said he tried to help you prepare!

Tests were tough but had a generous curve. Did a lot of demos and tried to make the material interesting. I would definitely recommend him!

He's hilarious during lectures, tests are tough but review previous classes and for final review previous exams-they are usually 75% the same exact questions.

He is a GREAT teacher. He makes class interesting and teaches very well. Lab is so HARD. Make sure to really read everything, and ALWAYS go to lab prepared, I failed my first two labs because I did not do this, and I failed my first two labs. So, be careful on labs. Also, if you do bad on a test, don't worry! He curves very good!

Awesome professor! His tests are hard, but the curve is amazing. He makes chemistry easy and he is super good looking! Take his class.

Massari is amazing! His tests are super hard, but having him as a professor is so worth it. He explains things in very simple terms and is a great help. He is perpetually entertaining, and it's obvious that he's enthusiastic about what he does. One of the best professors/teachers I've ever had.

Great Chemistry teacher. The honors course was very difficult, but that was expected. He did a great job helping everyone through the class, and even set the class average for the curve at an A-. Would definitely recommend.

Massari was an amazing professor - the best during my freshman year by far. Chemistry is naturally a difficult topic, and the honors version is certainly no easier. However, Massari was an effective teacher and, most importantly, was entertaining. Highly recommend!!

I didn't realize it at the time, but after going through multiple chemistry courses since, I now realize how great of a professor Massari was!He has a funny/awkward sense of humor that makes the class interesting and he is really helpful at office hours. Would most definitely take his class again, and that's coming from someone who hates chemistry!

He gives the most generous curves! He gives great lectures and tries his best to make the material clear and understandable.

Amazing professor that has passion and wants his students to succeed. Lectures are funny and really in depth. Tests are curved, they tend to be difficult, but he does a good job adjusting the grades.

Massari is a very funny guy that makes chemistry tolerable. It can be a hard class at times but Professor Massari does his best to help everyone understand. He sometimes goes on tangents describing derivations that waste class time but that is fine. I would say he is one of the best chemistry professors on campus.

Massari is a great professor who wants the best for his students. The class is in a huge lecture hall but he tries best to make it seem smaller. He's very willing to accommodate and helps you pass. Must do well on the exams; they account for 75% of the points. His exams are hard, but fair. Practice exams and office hours help!

He's great if you like a little humor in relation to the material your learning. Also, the demonstrations you do in the lecture are fun. More seriously the class is test heavy with a test every other week. He always tries his best to answer questions.

I won't lie this class is hard with a capital H, it's chemistry after all. But Aaron tries his best to make it understandable. But beware of those tests, walk into one of those unprepared and you're done for. At the end of the day it's a chem class and he works with what he has. But seriously those tests are land mines to your grades.

Arron is a pretty fun lecturer and will try to help you get the best grade you can. His lectures were sometimes hard to follow and didn't always cover all the material- but he always posted practice exams and lecture videos which were super helpful. Book practice questions are very helpful but don't bother getting the newest edition!

Professor Massari was a delight to have. Although the content was sometimes difficult, he always made sure to explain every concept and answer questions that people had. He provided a lot of additional resources to ensure we were successful. The tests are hard, but not impossible if you study. Overall, an awesome hilarious professor.

Aaron tries to make the class as interesting as possible and adds funny side jokes here and there to make it so. If you pay attention in lecture, take notes on the relevant Aleks topics (even though the online Aleks homework is a pain), and do the practice exams he provides, you should be all set.

I was enrolled in the hybrid class with Dressien and attended her once a week sessions for about two week until I switch to Massari's lecture. It was definitely the best choice. My lectures were at 8 am but that didn't matter because lectures were super interesting and all the content in class was helpful for the exams. I owe it to him for my grade

Professor Massari was amazing. I'm not a fan of chemistry but have to take lots of chem for my field, and Massari couldn't have made this class better. It is VERY HARD though so be prepared. Also, lots of people gave up on coming to lectures towards the end of the semester and missed out on some great jokes because this man is actually HILARIOUS.

Aaron really cares about his students. He does his best to answer questions and help people out. He doesn't take himself too seriously and tries to make lectures engaging. The class is fast paced and requires you to put in work and stay on top of things. I took this class without taking AP chem and was able to get an A.

My main frustrations with this class were not with the professor, but with the online exams (which aren't his decision) and the ALEKS homework. Massari's lectures are funny and informative, making this a good class to have at 8 am. Although lecture content at times didn't show up on exams, most of it did and he did his best to prepare us well.

Professor Massari is a very good, respected teacher. As I went to just about every lecture, I did learn that going wasn't exactly necessary because his slides are accessible and the book really helped me prepare for all the tests, but he does go over some problems and the demos are cool. The tests weren't bad , but the final was pretty tough.

He is a great lecturer and does a great job presenting material and answering questions during class. The demos are very good, but watch out for chem lab! The grading standards for chem lab are terrible in my opinion.

Great explanations.

Professor Massari was excellent. Great lectures and a lot of practice problems that went well with the exams. There were a lot of demos to keep us engaged and I left this course much more interested in chemistry than before. If you are debating whether to take 1081 or 1061 with Massari, you definitely should take the class with him!

Great professor who knows the subject matter well. Offers entertaining demonstrations just about every lecture. Online midterms every 2 weeks, making up most of the grade besides the final. Tests are fair but a bit on the hard side, grading expectations are fair, just be sure to finish your ALEKS homework each week.

Aaron is definitely your best option for CHEM1061. You can tell he cares about his students. He is also hilarious. His lectures are entertaining and he explains the content very well. Also, I took the class online, but I thought it was set up with a good online format. I didn't read the book once, but the book problems really help for the test!

Professor Massari is so amazing probably one of the BEST professors I have ever had. I'll be honest if you are taking Chem 1061 go OUT OF YOUR WAY to get him, your grade will THANK YOU. I got a B+ in chem 1015 while studying my BUTT off but with Massari, it was less work to get an A. You do have to study but it's a lot better than other professors!

Professor Massari was a great CHEM1062 professor. He was incredibly kind, understanding, and very approachable if you were ever confused about something. His lectures almost always had a fun demonstration. My only complaint is his online lecture videos can be spotty audio wise, so I'd recommend attending in person.

Out of all the chemistry professors for gen chem, Prof Massari is definitely the best. Chemistry isn't easy so don't expect it to be, but he is very caring and funny, which makes the class easier when you need to go for help. To get an A, you need an 86% which is super lenient compared to most gen chem professors. Highly recommend him!

Massari cares about his students and is really passionate about the stuff he teaches. He does pass over important parts of lecture assuming you know it so if you're lost-ASK QUESTIONS. He is really good at answering them. Overall, his lectures make a lot of sense despite being a hard concept and I would recommend him over Pelton 100%.

Overall a very solid professor, and certainly the best option for general chemistry. If you pay attention and take good notes in lecture, you'll be just fine. Prof. Massari is a really friendly guy, so never hesitate to ask a question if you're lost. If you put in the effort to study for the quizzes, they're pretty straightforward.

He is very kind and wants the best for his students. If you are willing to try in this class you will pass. If you complete all of the homework assignments on ALEKS that is a huge portion of your grade. The content for CHEM 2 is difficult but Aaron is a great professor and you should take it with him if you want someone kind teaching you

Aaron was a great professor to have for this course. Because it is on the more difficult side in regards to the material you are learning, I think he did a great job explaining and answering people's questions when they had them. Lots of points are available with the homework, Full Pie, and quizzes.

He is the best chemistry professor I've ever had. Really cares about his students, provides excellent feedback, his lectures are so in depth and he takes the time to explain everything

For how difficult Chem 1 is, Massari made it very manageable. He drops a midterm which is amazing if you mess up one really bad. He's a great lecturer and actually cares about his students doing well. He posts a recording of the lectures on canvas, and makes really helpful exam study guide sheets.

Great proffessor

His lectures are helpful, and the ALEKS homework is painfully unnecessary at times, but if done with care, the homework alone can prepare for the midterms.

He's a really helpful professor; his lectures are a must-attend because he goes over many practice problems that help you prepare for the exams. I would highly recommend this professor to anyone and would recommend doing the practice problems; try to finish Alkes as fast as possible because they are not that helpful and can be a waste of time.

He makes lecture fun and interesting with his dialog. During office hours (in person & online) he provides great feedback and tries to help you in any way possible. This class is reasonably difficult, but as long as you do the alkes and do the practice problems you should be fine. He's an amazing professor and is the best out of all chem teachers.

Massari is the literal GOAT. He does a great job answering questions without making you feel like an idiot. If you have the choice to, take a class with Massari because he's awesome.

So glad I am taking him again for chem2 after chem1. Enjoyed his lectures so much last semester it was more than worth to continue. Explains very well, can go a little fast sometimes, he does record lectures so that we can see them later.

if you get the chance to take your classes with Aaron then you should. He's a passionate lecturer who always tries to engage with the class, explains things very clearly, and always has an engaging demonstration for the course work at hand. The course is hard no matter who you take it with but Aaron will do his best to help you succeed.

Aaron was hilarious and cares enough about the coursework that it makes you want to care. Practice problems are definitely helpful for quizzes, and so is going to lectures (or if you don't want to go watching them online). He's good with feedback and a fair grader.

The only time I have ever intentionally chosen a section to have a specific professor.

There are not enough good things to say about Professor Massari. Genuinely the best professor I have ever had and an even better person. Although the class is challenging, he prepares you incredibly well for the exams and wants you to succeed. Always willing to help over email or outside of class, and truly cares about you as a student and person.

Aaron, my boy, was such an amazing professor. He was very helpful during office hours and painted material very clearly. Lectures mostly consisted of going over problems, and he cuts right to the gist of every lesson. Very clear what will be on the quizzes. Would totally take him again!

Aaron is great at explaining topics and was helpful when people would ask questions during class. The downside is there's loads of Aleks homework to complete that don't correlate with what will be on the quizzes. As for the final, I felt he did not properly prepare the class for what was going to be on it which would explain the 40% average.

One of my fav professors from my 4 semesters at the U. Great lectures with fun demonstrations, funny guy w/ good sense of humor, very kind and helpful when you ask him questions. Tests were tough, but do all your ALEKs, spend time studying the practice problems, REACH OUT with questions, and ez pass

Chemistry is overall a hard topic but Massari made it really fun. Does a bunch of little experiments in lectures. Super knowledgeable and caring. Easy to access outside of class, even sent me a Zoom link after I told him I was crying over my quiz. Super nice guy

Dr. Massari is the only chemistry professor I've had that I genuinely learned from. He explained subject matter clearly in multiple ways, so that any student who tried could understand the concepts. He was very understanding and did his best to help each student in the course succeed. I truly could not recommend Dr. Massari enough for this class.

Ok, compared to Pelton, Aaron is an amazing professor. Chemistry is hard and everyone struggles with it but atleast Aarons lectures are interesting - I actually laugh in them, bc he's seriously so funny. If you have to take any chem course and Aaron is an available professor, REGISTER.

Aaron is a really nice guy, by far the best chemistry professor I've had here at the U. The tests are hard because there are a lot of things that don't correlate to the lecture. A lot of homework and in-class worksheets allow you to keep your grade manageable. I would highly recommend Aaron, he's a cool and funny guy.

Aaron is hilarious and actually very interesting. I really enjoyed his engaging lectures and funny stories. He creates a really good classroom environment. Exams are tough, but go to lecture and focus on the homeworks and you should be good. If you have to take 1062, I strongly recommend Aaron!

Aaron is a G, and is easily the most entertaining professor I have had here at the U. He makes you look forward to lecture and is pretty understanding of any issues you have outside of the course. Definitely stay ahead of the assigned work, review with friends, do the practice questions, the worksheets, and you will succeed in the course and exams.

He was a great professor who made me understand chemistry! He also was hilarious, and the experiments mid-lecture did a nice job of breaking up the long lectures.

Massari was a saving grace in an otherwise awful chem track; presented material clearly, hilarious, and was very personable. Attendance isn't necessarily mandatory since he posts class slides, but the daily worksheets that have to be submitted during the class period will be harder to complete if you don't go. Take him if you can!

Dr. Massari is a very good lecturer and very accommodating to students. My largest issue with this class was the format, with Dr. Pelton recording all the lectures and writing all the exams. Many exam questions are not ever addressed in the lecture content, and the lecture videos are brief and do not give you the information needed for exams.

Massari is a great professor. His lectures provided much additional insight into conceptual and mathematical ideas in the class. I do think, however, that he tends to be a bit rude over email. Overall, way better than CHEM 1061! Take him if you can.

Aaron is an amazing professor, and made a difficult class enjoyable.

He makes lectures very engaging and dumbs content down enough so that everyone can understand. He also will repeat concepts a few times to make sure students get it, and is super open and detailed when you ask him questions. He provides marked up slides in case you miss a lecture and is a very good professor in my opinion.

Aaron Massari genuinely gives the UMN chemistry department a better reputation. If you have to take Chem 1062, I'd suggest taking his class if you can.

My king! I will really miss this professor. His lectures make general chemistry understandable and even fun. He *might* sound a bit rude over email, but he doesn't mean it. He is kind, funny, and caring, and he even excused me from assignments when I was unwell. Taking his class at 8 AM was totally worth it! :)

Massari is the light at the end of the tunnel. The chemistry department at the U is organized in the worst way possible, so unfortunately a big part of lecturing is taken up by those darn freaking worksheets, but when Massari gets a chance to lecture he is FUN and PATIENT and explains everything extremely well. Take him if you have the chance!
