good teacher, assigns a lot of homework, tests are challenging, but you will know the subject well.

G squared.. as we like to call him, is awesome. Gary is very helpful, very smart, and teaches the material well. though his tests and quizzes arent always the easiest

How can you not like this guy?

This guy was awesome. He told a lot of cheezy jokes while teaching his math. He did plenty of examples to help students prepare for tests.

This is the best math teacher I've EVER had. He was always there to help me and made lectures interesting with his mild humor. Tests and quizzes were fair. I would recommend him to anyone.

Great teacher, knows his stuff. Idiots will dislike him because he actually expects his students to learn mathematical concepts. If you want to understand math in any REAL way he is great. His lukewarm intensity is also quite entertaining.

He is a very good explainer

Mr. Grohs was honestly the best teacher I've ever had. His teaching style was very structured and efficient. He was always willing to help me, no matter how many times I bugged him. I would recommend this teacher to anyone who wants a clear understanding of algebra.

HILARIOUS! But yea..I barley got a C. I liked him though..never collected hw...I don't know if that is good or bad.

Hard but fair if he see you make an effort. I hated math but he was always available for explanations, even a few minutes before class. He was very encouraging when I felt bad about a grade and I eventually began to enjoy the class. I got A's! He was funny in a technical way and now I have a complete grasp of algebra. I'm not scared of math!!

This teacher is pretty goodlooking!

A very good teacher. Can be really funny at times. A very easy class to pass because everything he teaches is basic and understandable.

Class was difficult at first has a weird teacher style and is pretty difficult. wouldnt round my grade up from an 89.9

Very good teacher, but can be difficult. He explains things well, but expects work out of the class. If you do all your homework and pay attention in class, its pretty easy to pass.

some of these comments are a little harsh. no need for name calling. This professor is one of the sweetest, most intelligent people I've ever met. he teaches to a more advanced audience, so if you don't have your basics down don't bother taking him.. helpful, always answers questions. DON'T fall behind on the hmwrk because you will be buried alive!

His class is the best I have never had, and he is a great teacher because I have learned more than any class I have taken. He has great sense of humour and makes class laugh a lot. He expects me to learn something and is always helpful when I ask question. He is smart man and knows what he is teaching, and is certainly not a teacher only gives you

good teacher. clear instruction, helpful, and funny sometimes. If you want get something from the class but only grade, take him. certainly he will not pass you if you don't do anything after lessones

He is a good college level teacher, does not baby sits students but is helpful. I am losing respect to this site due to some students’ immaturity and ingratitude. It it a site for people to get information of finding good teachers depending upon the definition of good, but a site of venting anger, frustration and immaturity. Be grown or be home!!

I found this teacher to be very difficult. He goes through material very fast. Almost too fast to take notes. He makes a lot of assumptions on what you know unless you say differently. Tests are difficult, theory questions, and difficult problems. Advice: Do not fall behind on HW. Know your definitions (memorize word for word), ASK QUESTIONS!

Easily the best math teacher at ECC. everything he explained, he did it thoroughly and left out little to no info. his tests and quizzes can be tough, but his grading is justified. if you take your studies seriously, you should have no problem with him. he prepares you well - i got a B in his class, but went ahead to calc 2 and got an A

He was a great teacher. Don't miss his class because it's easy to fall behind. Nobody can read your mind so unless you speak up... he'll never know your having a difficult time. He is willing to do what it takes to help you through the course. He moves through material quickly, but is ALWAYS willing to help! He's a great teacher!!

good teacher. Class was kinda hard but he is willing to help. Just study for test and you will be fine.

Lets just say very challenging, not impossible though. If you enjoy mathmatics then take him. If you just want math to be a breeze then not highly recommended

Organized and fairly helpful, explains things clearly. He is a good teacher but wants dedication. Do not expect sympathy if you skip class or don't do homework.

Makes you work for your grade, tough class but it isnt impossible. willing to help outside of class but you have to ask. must spend time outside of class and homework practicing.

He is not the teacher to take if you want to just coast by and get a C. If you put in the effort and enjoy the subject, you will leave his class with a better understanding than you would get from most other teachers.

This professor is very smart and helpful if you seriously desire to learn and grow your mathematical foundation. He expects you to read the text and do the homework and considers the learning process a partnership between teacher and learner. If you want to pass and get easy credit by passively sitting there dont take him.

Fantastic teacher, learned so much from his lectures. Recommend this teacher, but NOT an easy A class. Put the work in, and it will pay off. He is more than willing to help you.

Great teacher and a great guy. He went very slow and was very thorough and understanding to anyones needs. The homework was all on MathXL and was easy and taught you a lot at the same time. His tests were very fair and he allowed days before each test for lectures to review everything. Very fair and very good teacher.

A hybrid class which demands outside of class completion of homework and watching videos. Lectures much better than the videos as I depended upon them to get me through the course. Professor Grohs is really caring and will go the extra mile if you are doing your part. Not a class to expect to pass if you just go there to sit and not be active.

This guy is excellent and fair. I signed up for a hybrid course knowing it is fast paced and cant complain. I barely passed with a C but I did not do all the homework. Students in the class did not seem to care and often came to class with no questions and no interest or concern about the course. Not sure they expect if they put nothing into it.

Math 112 is a difficult subject to begin with. He is very thorough when lecturing. There's homework everyday and a quiz at least once a week. He is very fair, and if you really pay attention, everything will seem fairly easy. I enjoyed his class and would recomend him to anyone who actually wants to learn.

He assigned optional homework out of the book every night but you better believe you should do it if you want to pass at all!

Took his hybrid class which is ok if you're self-disciplined to teach yourself with all the available resources that are given. Very fair teacher, wants you to succeed. Do ALL your homework, it counts as 1 exam grade in the end!

Intelligent. Take him if you want to have a professional career some day.

I took professor Grohs because I heard students saying that he is fair and knowledgeable, teaches you how to study math, encourages you to put education at a high priority in your life and so far it has all been true. Great teacher but you will need to do homework! Super sense of humor makes class fun.

He was good at explaining the material but the quizzes and tests are all short answer which makes it very hard. The quizzes are based off of the homework from that week but the tests are a lot harder. Need to make sure you stay on top of your homework and have a lot of time on your hands. Overall he was not a horrible teacher but fast pass

Total boss. Incredibly helpful, very instructive, great teacher in every way. His expectations are high, and he has little pity for those who don't do their work and subsequently fail the tests, but it's worth the effort to do well. One can tell that he seriously cares and enjoys math, and I think that's great. He also has a decent sense of humor.

He was an okay teacher. I had great math teachers in high school, which helped a lot. Before tests, he gives you a review day and he loves when you go up to him and ask as many questions as you'd like. He makes you feel stupid at times, but as long as you keep up with the online homework and ask questions you'll do fine! I got an A.

Best professor I've had so far. His class is not easy and he sets very high expectations. However he's very helpful and sincerely wants us to do good. Calc was my worst subject but he pushed me to do well in his class. Deifinitely take his class if you value hard work and a good sense of humor.

Wow, what an incredible experience taking Grohs class. I never enjoyed math as much as I do now because he made it so interesting. I worked harder than in other math classes at ECC but I also learned a lot more. I got my monies worth and more. I wasnt going to take more math but now i am planning on taking calc II.

He is the best calc person i have ever known.

Professor Grohs is a very knowledgeable individual in mathematics. It is better to take his class if math is your strong suit and/or you have a strong foundation. If you have your basics down, he can show very useful shortcuts. He has high standards so don't expect to pass without putting an honest effort into the class. Be sure to ask questions!!

I think that college algebra was probably one of the best math classes I have taken. He does a good job on teaching. To me individually, he was always there to answer questions. I hate math and I am very bad at it but I actually achieved a B in his class.. he was overall great

I took calc first semester right out of high school and found it awesome and a great challenge unlike my high school classes where I did not do a thing. I learned math and how to study at the college level so feel this was a good first class.

Professor Grohs is extremely smart. Sometimes he goes through the lesson a bit quickly but he is always open to anyone coming to him with questions. He went above and beyond to help me out and he is very nice. His course is a little tough but I think he gives you a better understanding of the material than other instructors.

I enjoyed the class throughout the semester and he was my favorite professor. The class is very demanding, you have homework everyday from "MyMathLab", anywhere from 10-45 problems a night. His tests can be challenging if you don't know the material inside and out. He sometimes does go too fast in his lecturers but he is very very personable.

Great professor. Very helpful. curves tests.

Good guy. Make sure you bring in your questions otherwise he will get mad fast. He curves everyone's test grades and will structure the class in differently throughout the semester for the benefit of the students.

Professor Grohs is everything you can ask for in a math teacher. He's helpful and very respectful. He explains subjects pretty quickly and it can be hard to follow along sometimes. However, he's always more than willing to stop for questions and rewind the lecture if you're left dazed and confused. I'm taking his class again this semester.

He goes into depth when explaining why we do mathematical operations. Very helpful but does go fairly quickly.

I took his hybrid class, and it wasn't too difficult. He is there to help, and wants you to pass. A few lame jokes here and there, but an overall good guy.

I took his hybrid class and loved it. You have to be very dedicated in a hybrid class because you have to complete the lessons on your own and class time is used to cover any issues you encountered. He wants his students to pass and is always willing to help. I loved his class and I have always struggled with math.

Get your monies worth by taking this guy and be prepared to do homework.

took his hybrid class and it was fairly easy. never used the textbook. and is very lenient with homework. if you ask for an extension you'll most likely get it. cracks lame jokes sometimes but explains everything really well.

Mr. Grohs is a great professor. He's good at explaining but can be fast-paced. Grades are based off of MyMathLab homework, the average of the best 10 quizzes, and 5-6 exams. MyMathLab was pretty demanding but it's worth it if you want to do well on his quizzes and exams. You should do fine if you keep up with the homework.

I took the hybrid 098 class and he was very easy to understand. He gave you his expectations from day one and if you do the homework (it's a lot) you will pass! The tests questions and the homework questions are similar. He drops the lowest test score and quiz grade. If you meed more time to complete the homework just ask him!

Listen, chances are that if you are looking at calc-professors you are more than likely going to be a STEM-Major. If you are looking for something that is easy are you really progressing in your studies? This teacher will make you think for yourself, and will not hold your hand throughout the semester. If you want to learn Calculus, take him.

I really appreciated how much he cared for his students. Even though I wan't doing so well in the class, he still told me to pursue engineering. He made sure that I was able to see him out of class to review quizzes and tests if I missed the day he passed them back. He didn't mind helping me with questions from past materials. He is one of the best

Very smart, very lenient, makes it very easy to pass College Algebra. I often talk to him before class and give him feedback on if we're ready for any quizzes and he has always given us more time to learn the material. He is very friendly and will work with you to help you pass! He makes it very east to pass if you just show up and do the homework!

Grohs is a very smart man who is passionate about what he teaches. His class takes up plenty of time outside of class, but if you do the homework assignments, study, and attend class, you should be able to do well on exams. Grohs is always willing to meet with you for his office hours and help you out if a problem is not clear. Don't miss class!!!

Get real about your future and take classes to learn or live in a dream world, be a loser and work as a cashier at Walmart for the rest of your life.

Not an easy teacher but knows his stuff and gives clear expectations.
