He is a very hard teacher who gives a surplus of information. His review sheets are very long and don't pin point what to study. If you were to do everything his study guide wanted it would take you a week to finish. Don't ever take any of his classes. If you do be prepared to work and study a lot.

Horrible Teacher! I have been in his class for about 3 weeks and I hate it! Do not take a class from him. His homework is so vague, hard and takes so long!

A really HARD teacher. He assigns homework, normally before he actually teaches the material. Expects you to study/do homework for about 9 hours each week for his class. Powerpoints barely cover anything that you need to know. Doesnt tell you what you did wrong on the test/homework.

DO NOT TAKE THIS CLASS!! I'm an A student, Phi Theta Kappa, and I had to drop this class before I failed it. That and when I needed help and emailed him he would either ignore my email or make me feel foolish for asking questions in class.

Do not take this professer especially if you need an A. His class was the hardest class I have taken so far his test are beyond hard and the homework doesn't even even out the tests. Do not take his classes.

I failed every test, badly, like 40% ish, did bad on quizzes, but A'ced the homework and last big assignments thankfully to the internet, and passed with a D.

horrible class. boring and hard. the notes were awful, he abbreviated everything so much you couldn't understand what it said. he talked super fast and only goes over things once. he expects you to know everything prior to the class. it all was very distasteful.

Horrible teacher! I just recently started his class and im greatly regretting it. I cant understand him in class and the homework has nothing to with his powerpoints. DO NOT TAKE!

David Voorhees is a terrible teacher. He does not give enough time to copy down notes. His tests are extremely difficult. The tests are over 5-8 chapters at a time. Overall I would never take another class of his in my life.

The worse teacher ive ever had.He mumbles half the lesson,so you have no idea what hes talking about.He yelled at our class because we ALL failed the test. Maybe he should realize that if his whole class is failing his test maybe its not the students maybe its him.I was thinking of printing off everyone's comments and giving them to him.

Worst teacher!!!! He stutters like a tard the whole time he is teaching. He grades extremely hard, I think he has a vendetta against his students. His beard makes me sick I would actually try not to look at him most days. TRUST ME DO YOURSELF A FAVOR AND DO NOT TAKE HIM!!!!

As a straight-A student at U of I, I took this summer class to get ahead and it was awful. It's impossible to do well not because the material is hard but because Mr. V is an ineffective teacher. It's painful but familiar to read these comments and see how many students struggle in his classes. He should seriously rethink his career choice. Teachers like this are why students dislike school.

Worst teacher I've ever had. He makes it extremely difficult to even pass the class, let alone get a good grade. 1/2 way through the course 2/3 of the class had dropped. No one got above a B- Grade and if you asked him a question, he would treat you like you were an idiot for not understanding the material.

BAD BAD BAD. I took this because I needed one more elective, thinking it wouldn't be too difficult of a class. WRONG. I took his class online, but it was an effing NIGHTMARE. He doesn't help you, and he's full of himself and it a complete you know what. STAY AWAY.

This class is impossible! The tests are all online and timed which you have to take during your own time. They are extremely difficult and are very long, each test took at least an hour.

Not a good teacher at all. Knowledgeable about the subject but does not know how to teach.

Worst teacher EVER!! A ton of work that doesn't prepare you for the test. Pointless 9 hour long field trips that take away time from your productivity level. Worthless field trip assignments that rarely connect to what you are learning in class. Doesn't teach, displays a power point of which you are not sure of what material to completely retain.

This teacher does not belong at a community college. Honestly the most difficult class I've taken in my two years at this school. He does not help with review for the test and its not on the tons of material you studied. Worst experience at WCC so far.

This is the hardest class I have taken at waubonsee. He pumps out 60-70 slides a day, he talks so fast he can't even finish what he's saying. The tests are insanely hard and covers around 5-10 national parks. He also gives pop quizzes that pretty hard. If you want an A in this class you will be spending 9 hours a week studying.

If I had to take the class over again, I would have chosen a different professor. I am sure that he is an expert in his field but he is NOT a teacher. Tests had trick questions, super-specific questions, used vocab that was not in the text, and covered too many chapters. The quizes, that took the most time, were only worth 15% of the grade.

Unreasonably hard. Take a different teacher

Acts like this class is for an Masters degree.

This professor teaches this class as it is a masters. We had a lot of people in the class to begin with now we have about 11. The power points makes no sense because he does not write out the full words and he talks to fast. The test are on blackboard and can be taken at home but the test are to hard. Don't take him.

Professor Voorhees decided to assign a take home test wanting us to compute the half-lives of a log then graph our findings all the while study for his final. Keep in mind that this is a 100-level class. I have four other classes that I have finals to study for but here I am going on my third hour on this take home quiz and not even 25% done.

Lecture heavy. Homework is really tedious and he doesn't explain them well if at all. I have a good grade in this course, so this is unbiased. I am currently working on a take home test, that involves a 1 page single spaced essay, the weekend before finals. Also, the mandatory field trip is incredibly boring and lasts several hours.

For an introduction class, this class was one of the hardest i have ever taken. Im a pretty good test taker and note-taker, but his tests are on an entirely different level. His exams are ridiculous, he grades incredibly hard, his lectures are boring and uninformative, and his class just angers me. Take my advice and choose another professor.

Uninteresting stuttering lecturing that flew through the material like he expected us all to know about it already. I have never taken a intro class that has made me feel this much stress. Tests are all large and confusing at times. He gives extra credit but it feels like he gives so much to compensate for how many students don't do well.

I had to drop his class at the beginning of the semester I had gotten ankle surgery and he refused to accept my late work despite me being in the hospital. He said it wasnt his problem. Very rude.

Took intro to earth science with him and it was terrible. Talks way too fast and reads from a powerpoint that doesnt make any sense. Expects everyone to know all of the material already even though it is an intro class. Made the class so uninteresting. I would not take him again or recommend him to anybody.

This professor was terrible. He did not explain the material effectively and his notes were symbols instead of words. Because of this it was very hard to study for tests. The class was full (36) students and by the end of the semester there were 9 of us left. DO NOT TAKE HIS CLASS!

Teacher doesnt teach what is going to be on the test. He abbreviates words on powerpoints, which makes it very hard to understand content on the slides.

His syllabus course schedule was not followed & Blackboard he had a COMPLETELY different schedule neither he followed The online Mastering Geology docked you points if you got the question wrong Tests wouldn't let you go back to previous questions Dis. board you had to post to see class posts & wait 2 hrs to reply or else you get an F for it. AWFUL

Horrible teacher, horrible PowerPoints, doesnt know how to use technology whatsoever the guy cant even properly post a link. Told us a month before the final hed have the study guide up but didnt put it up till less than a week before the final. Pretty much every question I asked via email was opened and ignored. Ive never been so stressed

For a basic level astronomy course, his expectations were too high. The moon observation assignment and constellation ones required a huge time commitment. The multiple mastering homework he assigned every couple of weeks took hours to complete AND the same questions were repeated! He also docked points for repeating the question on the test.

The prof. started the course a week early. Canvas didnt let me in until the set start date so I was already a week behind. Prof. said he sent an email the prior week saying it was open. I didn't get any email - I double checked. This is a 100 level course and he expected me to read over 75 pgs plus quizes and posts in 48 hrs. Insanity. Avoid.

Being 100 level, his Astronomy class contains extremely challenging and difficult-to-understand material. On his slides and learning objectives, Voorhees prides himself in using confusing abbreviations and talks very quickly in lectures. The best part? He will throw a fit if students don't understand something on a test he didn't explain well.

Every single question on every assignment & test was a trick question that was meant to trip you up. So much so that I left each assignment overwhelmed and more confused with the material than before. The timed exams were absolutely brutal. The content is so broad and overly specific far beyond an 100 level class. Very contradictory. Please avoid

Professor Voorhees has way too high of expectations for a level 100 class. I'm trying to simply pass this class for the science credit, I don't want to be an astronaut. He is a tough grader and threatens his students on many of his assignments about referring us to the conduct board. Save yourself and do not take this class.

I've always done very well in any class I've ever taken but this class was the hardest class I've ever taken. Professor Voorhees is VERY lecture heavy, goes very quickly, and explains the information to you like you're getting your masters, and you can't understand half of what's on his presentation because he abbreviates every word.

My grandmother passed away during the semester. As I was trying to support my family and struggling myself, he didn't help at all. He required documentation of my grandmother's passing for a little bit of leniency. I understand people may use it as an excuse for late assignments, but that's just ridiculous. Lots of self teaching online too!

Professor gave so much material to the point where it was overwhelming. It is impossible to be expected to retain that much information.

He's very passionate about astronomy, but it was terribly difficult to get through his lectures. He rambles, most of the time unclearly. His slides were very unhelpful, and looked more like speakers notes than helpful info. There was a ton of homework, and many of the questions were just pointless, sometimes opinion based and impossible to answer.

On hybrid day, all we did was fill out long page packets-that we had to complete b4 the hour was up. 1 time I didn't complete it & asked if I could finish it at home-he didn't understand. Took multiple times to try & explain to him, finally he understood. Then he got his things, turned off the lights, and walked out, and I was still in his room :(

Hands down worst class I've ever taken which was so disappointing because I really did enjoy the subject matter. I'm a 4.0 student and usually enjoy a challenge but professor Voorhees is the worst teacher I've had. I appreciate his passion for the subject but for a 100 class he grades incredibly harsh with no personal feedback.

his comments on your work are so unbelievably cryptic and full of hidden meanings and typos.

I would like to request that the student body at Waubonsee gaslight the professors of Waubonsee as punishment for wrongdoing. I am disabled! I do not keep my sheep! "I've had other students who were disabled and they did okay."-----Professor Jeanne McDonald

Professor Voorhees expects you to be at his exact level of astronomy knowledge (or hyper-fixation) and accuses you plagiarism for using the glossary of the assigned text as a reference.

I was eager to study astronomy, but Prof. Voorhees's outdated materials, disorganized objectives, and unclear, reworded exams made the course unnecessarily difficult. His dismissive attitude hindered learning. Despite strong performance in 12 WCC courses, this was my most academically challenging experience. Run and find another teacher.

Never forget. Never again.

This class was a lot of tedious work with not clear deadlines and a mess of a schedule. There were tons of typos in every single assignment, and he was a super harsh grader. No one got above an 86 on the final exam due to his strange question formats, as he writes his own questions. Would never take this course again.

Mr. Voorhees is very knowledgeable, and it shows. However, his lectures suck, all of the words are abbreviated, and you cannot read anything he writes on the board. You can barely understand anything he says. Attendance is not required but he will randomly post 150 points in class assignments and give you 20 minutes to do them.
