Run! Run from this man! His notes are terrible, endlessly talks but gets angry if you dont retain the info right then and there. Tests cover material that was hardly touched on and misleading (expects you to know the slightest details). Only 33% of class passed on first exam. Tries to show off how much he knows! DO NOT TAKE ORGO WITH THIS GUY!

I'd encourage taking him if you actually care about learning Organic. Slackers avoid, cause he will call you out for not doing assignments. His tests are doable, but you'll definitely need to study. No "read the chapter for 5 minutes and get it". And no "read the chapters the night before the test and get a decent grade"

Couple of Pro-tips for Dr. Etzkorn. He runs an optional review for the test the Thursday before the exam so don't have an evening lab for any classes. He sometimes reviews questions that will be on the test. The test is based a lot on questions in the book or examples that he uses in class so pay attention and study notes hard and go to every clas

Do not take his class! His grading is very strict and he has no rubric. He gives some people credit and others no credit. He expects you to know what to put in your 3 pages of notes from 100+ pages in your text book for every chapter.

Etzkorn generates so much bad karma for students. Respect yourself by taking someone else. He is also not of sound mind and prone to cause distress to countless persons, specifically females, he deems inferior.

Take good notes and try hard and you will succeed, recall that you are in a senior level chemistry and you must study and act like a senior. He is very caring and any effort is rewarded tremendously and I am proud to have taken Dr. Etzkorn this semester.

The WORST professor I've ever taken. He's a genius in orgo, but his teaching style is so ineffective: expects you to know complex topics before a lecture, teaches new material the day before an exam, and expects mastery. If you want to pass and not be constantly stressed out by a narcissistic professor, I STRONGLY recommend avoiding this class.

The professor offers no real help and directs everything back to the textbook. Lectures are disorganized, explanations are rushed, and questions are dismissed. This class isn't hard because of the material—it's hard because of how poorly it's taught. If you're not ready to teach yourself everything, avoid this course.

If you care about your GPA, PLEASE DO NOT TAKE ETZKORN. He's the worst prof I've ever taken. He is so negative, degrading, rude, and narcissistic. He NEVER wants to admit when he's wrong. He doesn't put grades on canvas and expects you to figure it out like..?! He's very uncommunicative, discouraging, and sassy in a bad way. READ the syllabus first

Outright terrible and makes you question your sanity. No matter how much you read and do the problem sets, his homework and exams are always harder. if you have no choice but to take him, save yourself by reading the syllabus before signing. This is his class and he makes the rules, so he can do what he wants without any repercussions.

Don't let the negative reviews fool you, I do believe Dr. Etzkorn is a genuinely nice man who cares for his students. Teaching style may seem intimidating at first, but it helps with how he presents his content. He appreciates effort and appreciation and that is shown by him basing final grades not only on raw score, but on other factors.

Dr. Etzkorn is a really tough professor. His test are hard, BUT he does cares for his students and wants them to pass. If you read the material, go to his office hours, and ask questions, then you should be able to pass the class. DO the problem sets in the textbook. Dr. Etzkorn knows chemistry and wants you to really understand it too.

This is a FAIR WARNING do not take him if you care about your GPA or if you graduate this semester. He discards a lot of important questions. He's also very sassy when asked certain questions. He has no PowerPoints just the text book and writes on the board. He expects highly of students when his teaching style sucks. Many people dropped overall!!

This is the hardest class I have ever taken. I have attended each of the sections for this course, and this professor is by far the hardest. His assignments and exams are much more challenging than the lecture and more challenging than the other sections. He doesn't give you your grades on Canvas, and you are forced to calculate your own grade.

Do not take this professor if you are a full time student. He is a very intelligent man. He teaches as if we already know the material well. His lectures are not like his exams. This class because of his teaching style. Those who are saying he's not that bad.. don't listen to them because they are not intended for the majority. Over half dropped.

His handwriting is illegible and he talks fast and moves on quick in lectures. No powerpoints so other than the textbook, which is dense and long, his lectures are the only resource. Tests are difficult and hard to prepare for due to the insane amount of detailed information. Not accessible outside of class or inside of class. Beware of Etzkorn.

Avoid taking this class if you care about your GPA. Not a single student earned an A, and I was one of only maybe five students who managed to scrape by with a C. Section began with about 40 students and ended with only 18.-3 exams, 1 extra credit project, and a final. Be prepared to dedicate a minimum of 3 hours every day solely to this class.

This professor has a big ego which directly effects the students urge to participate. He claims we should refer to the syllabus however he picks and chooses when to follow the syllabus. The grades were locked the entire class meaning we never saw our grade. Not even our final grade or our grade for the final exam or the grade for the extra credit.

People are not exaggerating when they say he is a very difficult professor. Lecture heavy, memorize all AA's, and plenty other molecular structures like Vit C, ATP, NAD(P)H, and FADH. But honestly, I'd say Troutman will also still be very difficult. Dr. Etzkorn is mostly true to the practice questions and does have a sense of humor! Study for sure.

Grading is not as tough now (2nd professor and a TA grade). I didn't do any readings at all. Even prof doesn't like the textbook and uses a different one for glycolysis. I relied completely on mastering things given in lecture and memorizing things mentioned in practice questions. Study like he|| and you'll pass. Do ALL sample questions given. ALL.

Dr. Etzkorn is the only professor I ever warn people about. You passing this class is based on his opinion, rather than number grades and he ended up only letting one person pass. Other professors even warn people about him. He is incredibly smart but cannot make the information easy to understand and provides no resources.

Unfortunately this professor expects his students to dedicate a ridiculous amount of time to his class every single week, please take this into consideration for your schedule. I dropped the class because of all the homework assigned and his expectation of students to fully understand the material before lecture (then why have class?).

A lot of what is said about him on here is true. His class is very difficult and you are graded essentially on three tests and a final exam (all compose about 75% of your final grade.) With that, you only need a 60% to make a C and, for the students who didn't withdraw, he gave a very generous 100 points of extra credit assignments.

Dr Etzkorn's class is more difficult than other teacher's 2131 classes. If you care about chemistry and want to learn the content, take him. Lots of homework. If you show up to office hours he will try to help you. He offers a lot of extra credit. I spent about 20 hours / week studying and doing the homeworks. Do all the homework, it helps!
