Dr. Sinner is a great teacher. He works some goofy stuff into his lectures without diverting from the topic, and that's definitely helpful in relieving some of the stress there is in anatomy and physiology. The material is challenging, but he's always willing to help and is very fair with all of his students. I would definitely recommend him.

Dr. Sinner made the class interesting and easier to understand. However, do not expect to get good grades if you don't put in the effort. You definitely need to study for this class but he's always there to help when needed. It's obvious he cares if his students get good grades or not. I would recommend him to anyone interested in this class.

Sinner was somewhat helpful. Sometimes he was unable to answer questions. He was also unclear on how some of our tests would be presented. He worked off of other teacher's material instead of creating his own. Most of the time he just read from the power point slides and didn't bother to give any extra information.

This professor was unclear of what he wanted from his students. You can tell he really doesn't have an interest in the success of his students.

Sinner has a carefree attitude that rubs off on his students. As others said he does not care if you pass or fail, it's on you. He definitely does not show interest like other professor's show, which makes an already difficult class more difficult. The reading from the powerpoint is terrible. Do not expect any other helpful tips.

This class covers a lot of material in a short amount of time. In order to keep up you must study daily. Dr. Sinner is very helpful if you ask him for the help. The class is big, therefore if you do not ask for help it will be easy for him not to notice you are in need and its our responsibility as students to speak up.

This guy is a great teacher. Anatomy is a tough course no matter who your professor is but Sinner makes the course fun. He is very approachable and allows questions. If you have to take A&P, whether you take it with Sinner or some other professor, you need to ask questions and get answers. You will always get answers with Sinner.

Have to study! Understand everything he says even those not included on the note packet.

If you want to learn anatomy and physiology, you will learn it here. It is a difficult class because it is a difficult subject. I did have to go to go tutoring and also watch many YouTube videos. He explains everything well but as mentioned it is a fast paced class. It was stressful & challenging but I def learned ALOT. Only failed one exam as ref.

Challenging subject! 201 is challenging. He did well explaining the material. You can rewatch his lectures online. You MUST study everyday for this class. I went to tutoring once a week. You have to understand the material to do well on exams. Its challenging but very rewarding passing his class!

Out of the A&P instructors at Phoenix college, I feel that Dr. Sinner is the most capable of giving those who are entering the medical field a well rounded and applicable education on the course material. He is challenging! More challenging than my 202 professor, for sure. His lectures online SAVED my grade in the class. You will work HARD!

In this class, lectures are provided already by other professors. All Dr. Sinner had to do was properly organize the course. He failed, completely. Five weeks in, he rescheduled every assignment, including ones that already happened. Every student would have done better if he had been better organized. Will never take a class with him again.

Very unorganized. Lectures are not his own material and he rarely posts in the class. He grades extremely tough and expects a lot for someone who isn't teaching his own class. Doesn't explain why he took away points and responds slowly. Highly suggest to not take his course.

Either you like him or you don't depending on your learning style. I think that he prepares us to use our time wisely and to dive into a subject if we want to get the most out of it. The best approach is to pre-fill out his lecture packet before class, and then absorb the material in class. This allows you to ask questions to gain understanding.

By far the worst online class I have taken. Very harsh on grading and does not give any feedback. When emailed or asked questions he takes forever to respond and gives a harsh/vague answer. Not caring at all. Exams and quizzes have so much information and the material provided does not help.

I was supposed to have meetings for this class but he switched it multiple times and I ended up missing a whole zoom because he never reached out. He isnt the kindest in his messages and does take for ever to respond. His excuse for not giving feedback on test and actually being a teacher was Covid.

The lectures arent his and barely cover half of whats on the tests so expect to have questions never talked about on the lecture. Then when you tell him his excuse is sorry I didnt make the test

Not my favorite Professor. Robotically strict with very little room for error. He's by the book with rules so don't expect much give from him. Will respond to emails but not always in a timely manner. Just stay on top of the work, videos and studying! Literally just listen to the videos until you know them by heart, you should be fine.

He loves it when students are struggling. He is thrilled when his course is described as hard by students. He displays narcissistic behaviors when fronted with criticism. He will go over the lecture only once, he will explain something only once, if you didn't get it the first time than it's your fault. don't expect him to explain in simple terms

Bio202 is a very difficult class and Prof. Sinner will make it even harder for you. I had to drop his class because I wasn't learning anything, he doesn't teach at all, if you don't have questions that's it, end of class. You do all the learning by yourself. He tells you to drop the class repeatedly instead of encourage you to do better. Awful!

Ok I gotta say I just took the class and passed it by myself got B+ not because the teacher no it's because I had prior knowledge of the human body so just letting you know if you have zero knowledge of the human body you will struggle. The teacher doesn't do anything he just doesn't care. I really liked when I took BIO 201 with Jason he cared.

I would steer clear of taking this class with James Sinner. He never taught not even once. I would take him as a teacher as my last resort. You won't get anywhere with him, and he never emails you back. I truly believe he doesn't care about the class nor students' success. I begged for help and never received it. Save yourself, go with someone else

All the negative comments on here are not dramatic but very true. He does not lecture and you have to teach yourself. He is more worried about you cheating and wants you to record your hands and screen the entire, time in that case just make us go in to test. Quizzes and test are given every week and is a very tough grader. I would NOT recommend!!

I had Professor James Sinner for a summer course, and it was a disappointing experience. He doesn't teach directly, relying on YouTube videos and PowerPoints made by other instructors. When asked for help, he often said it wasn't his material, which was frustrating. His lack of support and engagement made the course very challenging.

If you want a class that doesn't give you a ton of work then I would highly recommend. On the other hand you absolutely NEED to study! All of your grades are from quizzes and exams. He does give bonus questions on quizzes. He also answers any questions during lecture and lab. I would definitely recommend, but the course is difficult.

Professor Sinner was the worst professor I have ever taken. He does not care whether you pass or fail and just stands and talks. There is no hands on learning and all he truly cares about is yapping about football. He doesn't grade on time and rarely responds to emails. If you can, avoid him otherwise you're wasting time and money on his course.

One of the best teachers. Grades things on time so you have time to look over what questions you got wrong and work on them prior to the next class/ exam. It's an extremely big help when you can tell the professor puts in as much effort as their students.

this professor was the worst ive ever had. He doesnt teach and expects us to learn from a fill in the blank packet. He sucks at grading and steals lecture videos from other professors. He takes all of eternity to grade assignments and grades based on how he feels. I would rather sell my soul to satan or go to a diddy party than take him EVER AGAIN.
