too caught up with his self to even teach the class.

Terrible professor--He's got the lectures memorized so he rushes through everything, ridicules you and rolls his eyes when you ask questions. Treats the students with total disrespect and clearly has no social skills!!

Total Jerk! Rude, Condescending, Arrogant, doesn't seem to care about his students. He seems to see class as an exercise for his own amusement and enjoys confusing students in the process. Cannont answer questions from students without extraneous material.

he was not helpful at all, neither in class nor in lab

This guy is so rude . he also talks alot about nasty stuff like pooping

I spent 2 1/2 years at CCSC, graduated this quarter (Fall 2006) with an A.S. Blaha was by far the WORST teacher I have ever had including high school, college, and grade school.

This professor is a very easy grader. I all my labs, the ARIS assignments,and c in all the tests,but I got a B. He dosent help you at all, no attendence required for lectures which are useless anyway. You can show up on for the labs and tests. You would hate him but he is an easy grader...your choice.

the worse teacher ever in columbus state. please run away for the sake of your GPA

Please do not take this man class if you do not understand chemistry. I am a chemistry major but his class was useless. He also do not help you in lab. You are on your own. I got an A but just because I love chemistry and I teach myself. RUN RUN RUN from him if you do not want to hurt your GPA

the worst teacher i have ever had. He is extreamly disrespectful, answers your question with a question. you would be better of not asking him a question. his tests are very hard. never helps inlab. He seems like he doesn't want to teach at all, like he is beeing force to teach. RUN PEOPLE RUN DO NOT TAKE THIS GUY!!!!!!!!

Blaha is a very bad teacher who not only refuses to help you, he will openly mock you. His job is to teach you, but he spends every class telling stupid stories and talking about things other than the subject matter. He expects you to learn everything from the book and his lectures are completely useless. It is too bad he still has a job.

Worst professor I've ever had. Did not post grades to the class i had to look up my transcript to even find my grade. Unwillingness to answer questions. If you didn't understand something a general response is, " what do you mean you don't understand this? this stuff is easy". Do not take his class if you have a choice, You will regret it. Bad prof

Hands down worst professor I have ever had. His lectures are pointless, and he doesn't care whether you learn anything. I missed two classes due to my grandmother's funeral and he said "I don't care if it's your grandmother's funeral you don't miss my class because it makes more work for me". Truly a terrible person overall

Can't answer a question witst an answer, always another question. Doesn't cover the test material until 2 days before. If its on the practice exam count on it NOT being on the exam. He is very downgrading and NOT personable. AVOID IF POSSIBLE!!

very rude and unhelpful... lacks clarity! i wouldnt say he is very difficult, but i took gen chem 2 @ osu and found 171 to be more difficult. i can tell he hates teaching and does not give a sh*t. does cscc know how bad their chem department is? so many people fail.. not just a d but 30-40%. avoid.

I don't understand how anyone would want to take CHEM from this guy. He's a smart guy that knows absolutely nothing about how to teach. He cares nothing about his students, constantly talks down to the class, and is always asking pointless, unclear questions that are impossible to answer "correctly". Reading the book is the only way you'll learn.

Avoid this professor. Do not take his class. He punishes people for asking questions and being interested in chemistry. His lectures are worthless. He sits in the back and plays Solitaire during labs. He is rude. It's obvious that he does not enjoy teaching. He spends more time teaching math estimation than chemistry.

WORST PROFESSOR EVER. I had an A in the class overall, but literally flunked all of the exams except the finals which saved me. Passed with a C. Lectures? USELESS. Exam reviews? USELESS. A lot of self studying and A LOT of reading from the textbook. If you don't like to read (like me) I suggest you steer far far away from professor Blaha.

DO NOT TAKE HIS CLASS!!! His lectures have nothing to do with the tests and his tests are difficult. He goes off on tangents that make no sense and he has a bad attitude when people ask questions. Just take my advice and chose a different professor.

The WOST teacher I ever had. Please stay away from this guy. He doesn't teach. Goes off topic a lot. Very rude. Lectures are useless. You will not learn anything from him. Waste of time and money.

RUN AWAY!!! Do not take this guy as your professor. He is HORRIBLE! He never explains anything clearly and his lectures are a joke. He is rude and never explains anything. His tests are difficult because he doesn't teach. He should be fired. DO NOT TAKE HIS CLASS IF YOU WANT TO LEARN AND PASS!

I took his 1171 chem class and he is absolutely the worst professor or teacher I've ever had in my life. He never puts grades on ur papers, he always aanswers ur question with another question. He makes you feel dumb and brings you down when you don't know something. You better know how to learn from the book if you take his class. Avoid him!!!!!!!

This professor failed to help students in any way. Every time a student would ask a question he would answer it with another question in a condescending manner making it not only hard to understand the material but also causing students to feel uncomfortable for not understanding the material.

Its teachers like him that make people terrified to take chemistry. He doesn't teach his material well, when students ask questions to try to make sense of his lectures he shoots you down and belittles you, and thus the cycle continues. Students don't understand the material and the teacher wont help them. You need to love your textbook to pass.

Though I passed the course with a B I didn't understand his teaching what so ever. He very rude when it comes to questions being asked and makes you feel dumb for not understanding the material..If you want to do a lot of independent work he is okay, if not he is not that great!!!!!!!!!!!

If you want to do well in Blaha's class I recommend not going to class and studying on your own. I got an A in the class by reading the book, doing his problem sets and online assignments, and watching youtube videos for examples. Tests are largely easy if you prepare. Dont be intimidated by him, just study the material he gives you.

complete waste of time. managed to get a B in the class because his tests are 20 questions multiple choice and look a lot like the online homework. he's lazy and rude. I had a really hard time catching up in the next class because I didn't really learn anything from him. DO NOT TAKE if you have to go on to any additional chemistry.

Words that describe Professor Blaha: Rude, belittling, ignorant, impolite, inconsiderate and so on. He was no help to a teacher and when asking him a question he gave inappropriate, unprofessional comments. He made my semester miserable. Do not sign up for this so called "professor's" class.

This professor is rude and seems to enjoy belittling students. He does not answer questions and is as clear as mud in his lectures. Avoid taking his class at all costs. A separate room should be issued to this professor just for his ego. Students often read the book in class instead of participating because lecture is so unhelpful.

Do NOT take this professor. He is very rude and I was scared to ask questions due to the way he responded to questions. The lectures were useless and boring. The best thing to do is teach yourself the information.

Try to avoid this professor. He is rude and does not like answering questions. Many students are afraid to ask questions due to him being rude. The best way to pass is doing all of the work on your own. The lectures are useless and boring!

Every review about how horrible this professor is, is exactly on par with my experience in his class. Incredibly rude when answering a question, never passes back tests, plays games during lab, answers questions with more questions, I left this class more confused about chemistry. He is awful. AVOID AT ALL COSTS

I hate this guy

Worst professor ever. He plays games during lab. Doesn't post grades online and doesn't let you keep your exams after they are handed back. Always has time for questions but, if you ask he will respond with a question. Also, he does not write clearly on the blackboard, when asked to write clearer he said he did it on purpose so we would listen.

WORST professor ever. He does not explain one single thing. Doesn't even tell you how the class works and what assignments are due. Doesn't know how teach at all or maybe he just doesn't care. Not only that but he talks about women in a very demeaning way and generalizes women as if we were all the same. DO NOT TAKE HIM.

It is impossible to ask him questions. He is very demeaning and does not take to them very well. The class overall is fairly easy as long as you read and do the online work (the tests are very similar to the online stuff).

I would not take this professor, he does nothing to help you. If you ask a question, he makes you feel stupid and never gives you a straight answer. I had to use a tutor and teach myself the material because of his dry, rude and boring personality.

Dr.Blaha was not a very good professor. However, he curved the grade and helped me pass which probably wouldn't have happened if he didn't do that. It's VERY hard material and I had to get a tutor to pass. But he helped me pass so horray! If he sees you trying and showing up for class he will help you.

I love chemistry. I hate this guy. If you want to save yourself from trying to calculate you own grade and hoping you pass this class then don't take this class. He is the worst professor I have ever had. Save yourself.

ABSOLUTELY THE SINGLE WORST TEACHER ON EARTH. AVOID AND AVOID IF YOU CARE ABOUT YOUR GRADE. VERY RUDE AND DISRESPECTFUL TO ANYONE THAT ASKED A QUESTION. THERE YOU GO STEER CLEAR OF HIM

Terrible teacher and I won't recommend him to anyone.

He is unhelpful, condescending, and overall a waste of time. The only days where it was even remotely helpful to go to class were the days he went over the homework because it is exactly like what was on the tests. Otherwise it was one of the worst classes I've ever been in. Your best bet if you have to have him is to buy the book a get a tutor.

If you want to teach yourself, stay in his class. I learned more from reading the book and only showing up on lab days (only to turn work in worth points) than I did when I actually attended lecture. He does provide for easy points, but as everyone else has written, he is extremely condescending and does not take well to being asked questions.

Just Awful

This dude was horrible. The study guide and the test were two completely different things. He would make you think the test is more one mathematical equations than when you took the test there would be almost on math and it would be all concepts. The only thing that will save me in this class is automatic 100s on the labs. Do not take this class

I did not learn anything from him !!!!!!!!!!!

You will learn absolutely nothing from him but his tests are easy if you teach yourself from youtube. I would take again, just because his tests are easy and I have no problem learning from youtube.

WASTE OF TIME. Professor Blaha seems to care more about his solitare high score than his students who sadly have to pay money for his pathetic class.

Do not take his class. I am disappointed that CSCC continues to employee this "professor". Any question you ask will be met with "I don't know, do you?" or some variation, followed by a 20-30 minute long period of time where he continues to ask the question over and over to the students who don't know the answer. Stay FAR away. Dropped to save GPA.

Worst professor I've ever had. He doesn't answer any of your questions on the material and is very confusing about how he grades assignments. His explanations on the material will just confuse you even more. If you have to take his class don't bother going to lectures and teach yourself using the textbook and the internet.

The lectures basically won't help you at all. If you're the type of student that can teach yourself and read from the textbook, this is the class for you. If not, definitely don't recommend taking this class. The labs are hard because he doesn't really help you through them and they're just challenging in general.

Do not take this class worst professor you'll ever have

The WORST professor ever! If you want to get an A in Chem, do not take this class! I repeat DO NOT Take this class with Blaha. You have to teach yourself EVERYTHING. He comes to class with nothing but a Dr pepper.

Can't get any worse than this!

Worst professor I've ever had. I love chemistry and the CHEM1171 itself is easy, but his lectures were terrible and I ended up teaching myself everything online. If you have questions, he won't answer them. He doesn't explain well at all. He is very rude and sarcastic. I should have just taken this class online.

This "professor" is the worst teacher I've experienced in my entire academic career. He clearly does not care anymore, refusing to teach his class a single valuable portion of information. His constant tangents make the book a necessity. I've seen negative ratings on this website before, but this guy truly deserves every ounce of this criticism.

Literally the worst professor I have ever had the misfortune of having. Extremely condescending and expects you to know all of the material without lecturing, or power points. Lecture is an absolute joke. With that said, he is very smart, just does not pass on his knowledge to his students. DO NOT TAKE IF YOU CARE FOR YOUR GPA. YOU HAVE BEEN WARNED

Worst teacher I've ever had. He's very weird and a bit creepy. He doesn't tell you what he explicitly wants and he will stand in front of the class for periods of time if no one knows the answer to the question he has asked. If possible I would suggest another professor.

THE WORST PROFESSOR EVEERRR!!! DONT TAKE IT ANY CLASSES WITH HIM. THE LECTURE, THE REVIEW AND THE TEST ARE COMPLETELY DIFFERENT!!!!

DO NOT TAKE HIS CLASS. I REPEAT DO NOT TAKE HIS CLASS. If you want to pass then dont have him as a professor. He does no notes, only math problems on the board. He just talks at the class during every lecture expecting you to know what hes talking about. His tests werent always like the practice problem sets so you have to read.

I wish I had known about this site before I took this course. I have no problem saying that his class was one of the worse I have taken. Please read all the reviews because we are all saying the same thing. DO NOT TAKE. DO NOT TAKE. DO NOT TAKE. IF YOU CARE FOR YOUR GPA AND GRADE. DON'T. You have been warned.

He is that kind who assumes students must know the material. No power points, his anwsers to questions confuse even more. The whole class is about talking. I do regret taking him for this course. I wished i read the reviews before. Make sure you buy your book and have an unlimited internet connexion cause you about to study like crazy!!!

I wouldnt take this class again if my life depended on it. Ive never had such an unhelpful and patronizing teacher. My drive has been completely killed. One of the first things he announced in class is how many people drop his class, he really takes pride in that. Youll feel miserable, dont take a class of his.

I have this class right now and actually in class right now . This is how bored i got from his teachings. He does nothing but talk and barely writes on the board math problems he expects you to know . Someone said he brings nothing to class but Dr Pepper thats so true . Im trying to get the text book and just teach myself smh

I wish I could go back in time and get a different professor. He provides no materials for the students and he explains things in a confusing way. On top of that, he is incredibly condescending during the class period and has long awkward pauses. The only good thing about this course is how all the assignments are participation points.

Very lazy , terrible lectures

Ridiculous professor, creates difficult content and expects the class to follow lectures that dont even relate to the subject at task.

Expect a C or lower on all tests.. they are all multiple choice though and only 20 questions. The questions are not very related to what is taught in class. To study you should use the chapter review questions that are already answered on blackboard..

Don't take this teacher for any class, he goes on long tangent rants that have nothing to do with the material and he never answers questions directly. He isn't helpful and you'll struggle in this class even if you have a high background in the sciences. Hes also very creepy, talks about naked people often. Extremely pointless and a waste of money

The class itself is easy if you are someone who can just read from the book and teach yourself. If you have any questions or expect to get help from the professor, forget about it. Professor is incredibly condecending and makes you regret ever asking any questions or seeking help.

He makes everything more difficult than it needs to be, he won't answer any of your questions, you won't know when things are due or what he wants from you on the homework for the class. It isn't straightforward and he will not help you at all. He makes you feel like an idiot if you ask him any sort of question.

This man is hands down the worst teacher I've ever had. He is not understanding of those who do not follow his teaching style, which by the way is extremely messy and unorganized. He is an intelligent person, but this is a really big downfall with his class because he can't explain things to people who have a loose understanding of chem. -100/10.

Professor Blaha was the worst professor I have ever had in college. His lectures go off on tangents, he emphasizes math that is not chemistry-derived, makes you feel like an idiot if you ask questions, will not answer emails, says inappropriate jokes in class and takes something interesting and makes it a horrible experience. Stay away!

While it is possible to pass Blaha's class, it is incredibly difficult. You will need to teach yourself at home by reading the chapters. The best way to study for the tests is to practice the self assessments first, and then practice his problem sets. Even though he designs the problem sets, it does not have everything you need to practice.

I would not recommend anyone, especially not pre-meds, take his class if you need to continue on in the course sequence. He does not use slides, instead he just talks at you and if you don't understand you teach yourself using the book. Tests are multiple choice so there is no partial credit. Minimal feedback. Labs are graded on competition.

While taking tests he likes to throw little curve balls, or quiz on things that were in the textbook, but weren't said in class or were very briefly discussed. He would also never answer questions straight forward and belittle people when they did. Got my class to never ask questions because of it. The class as a whole was frustrating and annoying.

He is completely unavailable. Every time I reach out to him I regret it. He is rude, condescending, and tries to make you feel like an idiot for asking questions. I am taking the class over the summer and we can't meet because of COVID19. The class was supposed to be in person and he has not posted any lectures or real learning tools.

Here's how I passed gen chem 1: -read each chapter/ take notes -did practice problems in textbook -do all self assessments -do all problem sets Do all these things before each midterm. You're basically self teaching. Complete the labs and redo the self assessments before exams. The final is also not cumulative no matter what he says... you got it!

He did not set up a course that was conducive to online learning. His pre recorded lectures were incredibly dry and all of the material had to be self taught from the book. As someone who does not have a knack for chemistry I found this format to be difficult. He does not do a good job of "dumbing it down" for the average chemistry student.

Does not know how to teach chemistry, says he will grade for completion, miss one question and you will receive no points. During this pandemic, teachers have been available through collaborate to answer questions, hold online lectures he has offered no help, and said he will not being doing this. How is this teaching? We are failing its on him!

Professor Blaha is difficult to understand because he does not speak good english. He also told the class that labs would be accepted for completion, but rarely accepted labs unless they were 100% correct. Whenever anyone asked him for help, he responded in broken english that was hard to understand and was condescending.

For the love of your grades and understanding of chemistry... avoid Blaha. I am currently taking his online general chemistry class and everything is having to be self taught. His assignments and labs are confusing and his lecture PowerPoints are unclear and hard to follow. Even when asking for help, his responses are negative and unhelpful. 0/5

His class is set up poorly. Its impossible to follow and hes not helpful at all. Im teaching myself. All of his examples are just him reading from the textbook. I dont think he actually knows chemistry himself. If you want to do well take another chemistry class.

Hands down the worst professor I have ever had. DO NOT take his class. Not only is it incredibly confusing and terribly set up, any time you approach him with questions he sends back paragraphs of "advice" that is at best unhelpful, and it worst condescending and demeaning. If you want to keep your self esteem and grades, pick another professor.

I honestly didn't have any interactions with Mr. Blaha because he barley responded to emails. This class was really you teaching yourself because we didn't have any live classes because stated in syllabus it would be too much. Around last month he decided to start doing live classes to help people but at that point I think it is just to late.

I honestly have had little interaction with this professor because he didn't respond to my e-mails. We didn't have live classes because he said it was too much to teach in a sort time. You basically are teaching yourself, about a month ago he decided to start doing live class to help with questions but at that time I think it is to late.

Professor Blaha has been one of the worst professors. His lectures consist of answering questions in a way that no one can understand. Be prepared to teach yourself all the material and do the problems on the PowerPoint slides he provides. No need to buy the textbook because all of his slides are directly from the book. Labs are very hard.

WORST PROF EVER. doesn't care at all about his students and he will make you feel stupid for asking questions even though he's always begging us to ask questions. if you have another option don't take his class this semester has been the worst because of him.

This was my 2nd time taking chem after not doing the best at OSU. So I knew most of the material already. If I didn't I do not think I would have passed.
