This professor is not helpful. instead of helping the students he fail them for simply mistakes, he is mean. i had a very bad experience with him i pass all my other classes with A's and BX. but this guy fail me because i could not understand this stupid class. everytime when i ask him a question he would say i dont have time to stay on this.

He was one of the worse professors to have. If u buy his textbook it's useless becuz he doesn't from out of the book. He teaches his way and he will get lost. he post up hw on the weekend that's due on monday and he will put it on blackboard on sat or sunday night. doesn't know how to explain topics wi the class and expects u know everything about

He is very very hard on grading. i have been an A student for 3 semesters and my first B came from his class. Please don't take him, his teaching skills are bad

gives low grades no matter how many questions you answer in class.

he's Horrible..he attempts to teach from the book..hard on grading,anwers your question with a dumb question type of teacher..Dont Take Him!

This prof is a disgrace to all professors and the college. Ok maybe he's good in what he does, but he ABSOLUTELY stinks in teaching. He doesn't want to be bothered with questions and if he'll answer one, he does it with another question. DO NOT TAKE HIM!!!! Are you confused?????

Horrible professior. talk out of the topic. unfortunately qcc has only him for bu 520, bu 508. students has no way to avoid him,he is taking that advantage. very rude, and insult students in front of others,talk loudly then teach

Kolios is a hard professor.

Probably the worlds biggest piece of waste. This man will yell at anyone who asks him for help, he even yells at a student who is mentally disabled. It gets to the point where every student is afraid to ask a question. Only take this class if you enjoy feeling afraid.

His behavior is better then before with students, but most of the students fail in his class. He follows book in the class but exam different than class work , no extra credit. he doesn't check homework. i will not recommended him. you won't pass.

Professor Kolios is a very hard professor.

To be honest I dont knw what should I write about him. I dont have any good word for him. Just try to skip his class because he dont know how to teach but he think he is the best. please dont take his class . I suffered a lot so i dont want you guys suffer. all the best.

The worst professor ever! When i try to ask him a question, he won't give me an answer. He would even yell at his students if they had a question for him. His exams are confusing like crazy due to his poor grammar and wording. Lastly, his final project didn't make much sense to me when he explained it. This professor needs to be reviewed by QCC.

Very bad teacher the exam is totally different from what he teachers and when you ask question in the class he get angry dont take his class he will fail you

No good techer donot take this class

worst professor I ever took. He gets mad when you ask him a question, he expects you to know programming even though its and INTRODUCTION class. Goodluck if you take tbh i hope he leaves qcc and replace with someone who wants their students to pass.

i think this guy eats acid for breakfast. don't take him if you care about your GPA.

Students who have already signed up for CIS252 Spirng 2017 semester please drop his class because let's be real he is the worst professor of QCC, so the department drop this course from the spring term and we all can take the class which we are not allowed to take as yet.

Very bad teacher doesn't know any thing about computers he must be fired

I did not understand anything he taught in class. His tests were so hard for me. I don't find him helpful. CUNY Queensborough Community College should evaluate him for what kind of professor is he.

Very unfair grader, couldnt understand clearly.

He was unclear in his explanations and when you ask him for help he doesn't want to explain. I think he is not a good professor because he never cares on his students. I don't recommend him because i think we pay for a service his duties are to explain and answer the students's questions. He doesn't have a vocation as a professor.

Any other professor would be better. It couldn't get worse. Professor Kolios is the sole reason I couldn't keep my GPA at 4.0. Very unclear and uncaring. Confused about the topic himself. Avoid at all costs

Other professors would be a better than him. He doesn't explain anything clearly he can, he only does it to just shut people up. Why the hell is he still working here? He should be fired, because he's not teaching anything at all.

Prof Kolios teaches us 10% of the lesson and expects you to understand the rest of the 90% on your own. He does not give a textbook, so either attend tutoring and have David explain it or get a textbook from the library and GET READING

I couldn't get my GPA close to a 4.0. He wasn't clear in what he explains in the class, assigns in assignments, tests and projects. Because of his lack of effort in teaching the class my GPA got reduced from a 3.75 to a 3.5, which feels like I have been set further back from reaching a 4.0 GPA. If you care about your gpa don't take him ever!!!!!

He isn't very clear on what he wants us to work on in his class. He doesn't say much in the lecture class. He also has a personality that presents himself as somebody cocky in knowing about the material which he clearly doesnt.

He was very inconsiderate about my disability. Didn't give me any leniency when every other professor I took did. He is very erratic in his moods and if you are confused, he will have your head. Very rude professor and rude man at that. DO NOT TAKE!

One of the worst professors in the college. It is sad there are no other professors for the course. He teaches 10% and expects you to learn 90%. His homework and project have nothing to do with the classwork that he teaches. He is very rude and does not help students with projects. Never replies to email.

He just don't care about students and tough grader. Worst prof ever I seen

I withdrew from his class today due to his lack of comprehension and help All he ever says when something goes wrong for a student is " I don't know figure it out" and blames or points his fingers to someone else. He sucks as a teacher and his work makes 0 sense would not recommend even today during a test he would not help and has not answer

tough grader

A very disrespectful professor. Is not understanding of students and gets annoyed when students ask questions. Like why are you teaching if you get annoyed to teach? You have to learn things on your own or elsewhere because you are not going to learn anything from him. If you don't wanna mess your GPA, don't take him!

Worst professor at Queensborough Community College. Barely graded any of my assignments, and when he did, the grades would be low. Teaches 50% of the work and expects the students to understand the other 50%. If our roles were switched, I would fail him on the spot. Do yourself a favor and never take Professor Kolios.

he's the worst professor in the entire college. I tried to talk to him about work he gets mad. he doesn't record any of his lectures but shows other staff members he does record office hours. he gets mad when a student asks ant question. if he doesn't have any answer on the spot he gets mad and leaves.
