Thought he was going to be great when I saw his rate my professor but oh was I wrong. Always felt stupid in his class. We learn Gen Chem in basic chem and all the utsa tutors told me this. If you take, you will be so ready for gen but beware to have no life takint mamiya

This course was not even challenging, the struggle was putting up with the professor. He is so rude for no reason.

This kind of professor enjoys the power he has over students and uses his position (however low that is) to be cruel.

Needs a reality check. I don't know what he gets from being so arrogant and mean but I sure hope he does not act like that with everyone.

Very trail-by-fire teaching. He uploads videos that briefly go over the topic and then puts up practice problems throughout the lecture, if you have a question about a problem you don't understand he WILL outright ask if you're even paying attention. Attendance is mandatory, exams are tough but 5 questions are given, weekly ALEKS, daily quizzes.

Videos are not helpful, exams are difficult, a lot of ALEKS in very little time, doesn't teach in lecture, will call you stupid in front of the class, daily assignments, poorly answered emails, and will make you hate chemistry. Unless there's another teacher AVOID!!!

DONT TAKE THIS CLASS, HE DOES BASIC LECTURE VIDEOS AND ICLICKER QUESTIONS IN LECTURE AND WONT LET YOU SEE GRADES MAJORITY OF THE SEMESTER TILL HE'S REQUIRED TO .STAY VERY VERY FAR FROM THIS ARROGANT MAN

DO NOT TAKE HIS CLASS

Do Not take this Professor save your GPA. He is very rude, if he does like your question he will make fun of you and make you feel dumb. Chemistry is a hard course and he expects everyone to learn at the same level and pace. He does not teach very well and all he goes over is questions in class.

DO NOT TAKE THIS PROFESSOR. The subject is hard but he made it so much more difficult than it needed to be. he doesn't lecture in class, he post "lecture videos" on canvas, goes over the bare minimum in the video and when comes test day asks the most difficult problems. the way he words his problems is terrible, he will make you feel dumb. AWFUL!

he doesn't even see let you see your grade, he says "it disrupts your learning because you're only focusing on passing", like why else would i be taking the class. will make you feel dumb, doesn't lecture in class, post vague lecture videos then has very difficult problems on the test, and words his questions terribly. is available for office hour

This guy is a joke

Please do not take this course! Dr. Mamiya solely relies on Aleks and 3 minute lecture videos for you to learn material. Most of his lectures are nonsense, and if you ask a question he will make you feel dumb and make fun of you. The amount of aleks homework given is impossible to complete. This is the first class I have failed. DONT TAKE IT!!!!

Professor Mamiya only teaches via youtube videos and practice problems during class, he tests you on your knowledge by using i-clicker questions as attendance and participation grades. He's very condescending and rude and his reviews are nothing like the exams. If you don't want your gpa to drop, don't take him.

Does NOT allow you to see your grade until after the class is over, does not cover material well. Be prepared to teach yourself, as he uses ALEKS as his sole learning method. He has YouTube videos on Canvas, but that's it. Don't waste your money or GPA on this class. It's not a good class to take if you have outside responsibilities like work.

don't do it.

don't do it I BEG U

This should be the last professor anyone takes. Definitely the worst professor in the chemistry department and at UTSA in general. Do not take this class, you will regret it!

Highly recommend avoiding this professor unless you're coming into this class with a good understanding of chemistry. Nothing feels basic about this course and Dr. Mamiya will not baby you through it. The material itself isn't very complicated, it's the way it's presented. Test out of this course or find another professor.

This is not the teacher for you if you don't understand chemistry. Will purposely try to discourage you. Has threatened students at times. No notes or material will help you succeed on tests. Does have a "No electronic policy in place. ALEKS doesn't help you practice. iClickers are mandatory and sometimes makes correct answers count for credit.

Do not take this professor at all costs. PLEASE LISTEN TO THE REVIEWS, he is rated a 2/5 for a reason! This professor is not good at what he does whatsoever.

Legitimately the worst teacher I've ever had, but it's not like he tries to teach in the first place anyway.

If someone in your family passes that is out of state well your in luck! This professor will save you money and time by not letting you retake an exam another day. So instead of saying bye to my grandma one last time I took his exam instead. Expect to teach yourself, listen to him yapping about nothing, and if something goes wrong well tough.

As an A & B student this is the only class that I have ever failed in my life. Blain cannot and does not teach class. If you want to pass you have to teach yourself because he never teaches in class. He makes rude and sarcastic remarks to students and doesn't explain problems correctly,I would highly recommend to avoid taking his class if possible.

Dude TERRIBLE professor, I had to take a withdrawal because I couldn't take the impact it would've had on my GPA. He never told us what our grade in the class was and all he would say was "you're going to be okay." Made chemistry way harder than it should be. 0/10.

disrespectful chemistry teacher, I had a terrible experience in their class, and I strongly advise against taking it. The teaching was disorganized, and there was a complete lack of respect for students. I often felt belittled and unsupported, making it extremely difficult to learn. Save yourself the trouble and avoid this class at all costs.

The worse instructor I have had the displeasure of "studying" under. The feeling of entitlement and ego this person carries is way more than his passion for teaching and instructing. The class average during his semester was 50-60%, keep in mind this is basic chemistry. I only wish I took the ALEKS replacement test, instead of wasting my time.

Not someone I would ever recommend taking. Aleks due every day out of the week among other assignments. Not even my past Statistics or physics classes were as workload heavy as this. Will go an entire lecture with him rambling on how students fail, this is chemistry not academic advising. Extremely condescending, consistently gives smart remarks.

STAY AWAY FROM THIS CLASS AT ALL COST!!! I took this class and struggled the entire time, I would preview class, go and ask him questions during office hours and he would say it is just the way I am studying. He loves to see people fail, his ego is the 5% passing. Call Dr.Lamb if enough people complain, then maybe she will do something about it.

Do not take his class. He is not understanding to any circumstances whatsoever. You can talk to him as much as you want but he will not help you. He will just ask you why you don't understand the material and then continue to do a horrible job at explaining it.

He's bald and angry, but lowkey wholesome

He spends most about talking about things that are not even chemistry related. Then he actually begins to do "work" which he expects you to already know. And there is other better chem professors which students are doing great in, and you compare that to Mamiya and he is the problem.

Be prepared to be publicly humiliated in class if you're late. Doesn't matter if you can't control traffic or if there are accidents, he will blame you in front of everybody and shame you!

Do NOT take this egg head, this dude is the worst professor ive ever had, either CHOOSE SOMEONE ELSE, or just take the aleks. he doesn't teach apart from 4-5 min videos he posts, class is just him quizzing you the whole time, he also yaps for abt 20-25 mins at the beginning of every class. IF UR READING THIS, CHOOSE ANOTHER PROFESSOR.

Take the ALEKS or prepare to suffer in his class, he gives youtube videos and then expects you to know it by the next day, he'll blame the way you study, rather then to blame himself. He tells you to change how you study but really he should change his way of teaching bc ofc its not working.

wish there was a way to rate a professor a 0 even that would still be too kind for this individual. To name just a few issues: they are disrespectful, egotistical, and completely incapable of teaching. Their interactions with students are condescending and dismissive, and their approach to instruction is not only ineffective but outright negligent.

I wish rmp allowed for us to type more so that I can fully give you and idea of how much of a terrible experience it was having this professor

Terrible, big ego , never again

don't ruin your tests, or else your cooked in class.

Do not take him!! This class literally traumatized me!! Take somebody else!!

One of the worst leads for a department ever unfortunately. UTSA has a lot of great department heads who care and set you up for sucess but Mamiya just has the "I struggled so you should too" mindset. He is tough and words questions badly. He does not care if more than half the class gets below an A. I wish it was different.

Rate my professor doesn't allow extensive reviews, which is a shame. I say this mainly because this class is a mixed bag, and 350 CHARACTERS. wouldn't do justice towards the experience of this class. My main issues where that he hides your grades on canvas, and tests that don't check for understanding. Moreso attention to detail. Prepare early.

This was the absolute worst experience I have ever had in a class. The practice tests weren't like the exam, the homework load is insane, he gives less chances and grades more harsh

Whatever you do please do not take this class, this class has stripped me of my dignity I am not joking. Dr Mamiya seems like an awesome guy outside of class, I enjoyed conversation with him on topics like biology but please just save yourself and do not take this class just "Aleks out" and be lost in gen chem I because you'll be equally lost here.

I took him Fall 2024, be prepared to basically teach yourself, he prides himself on having a low passing rate, and he'll belittle you in class if you don't know the material all the way. save yourself the time and do the Aleks placement instead.

Professor Blain was rude, unhelpful, and created a hostile learning environment. Lectures were rare or uninformative, grading was unclear, and questions were often met with belittling comments. Students were left to teach themselves. I would not recommend this professor to anyone serious about learning.

Take this professor if you like to be yelled at, spoken down to, and publicly humiliated. To SDS students, AVOID THIS MAN AT ALL COST. He keeps the grades locked the entire semester and gives excessive assignments. He does not teach ever, he only quizzes and expects you to learn at home. He brags about his fail rate being over 50%. DO NOT TAKE!!!

disrespectful.

Gives a minimum of 10 assignments to do a week, some of which have absolutely nothing to do with chemistry. Knows what he is talking about, but is a horrible teacher, has a "you teach yourself" mentality. Grade depends heavily on ALEKS (daily), which is very inconvenient for people with other obligations. would not take again.
