Dr. Rosario was very nice and approachable. The class is hard, but he makes the material seem not as scary and manageable. He also curves the exams depending on how well the class did. Very open to feedback since he is new, and allows for some small extra credit on each exam.

Dr. Rosario is a very nice & intelligent guy. His lectures are interesting, but it is important to go to class to pass. Also, tutoring helps. This was his first time teaching this course, but I think he did a really great job of doing it and it will only get better. For the last couple tests he gave study guides, so he might do it again.

His lectures are interesting and funny, but the material of the class is difficult so you really have to study. His exams are hard but it's his first time teaching so I think he's making them easier next semester (spring 2019). He is helpful during office hours and I would recommend going to tutoring. Textbook isn't necessary but is helpful.

Rosario made this class so much better, I'd love to take him again. He genuinely wants you to understand the material, don't be afraid to ask questions! Exams follow the powerpoints very closely. Try and take notes on things he says that aren't necessarily written down and just study from that. Lab is hard, it's a lot of memorization.

I hated this class not because it's anatomy, but because Dr. Rosario is an AWFUL professor.

Once you take the test there is 1000 times more information on there than we learned or read. The lecture exams are so hard for no reason.

Dr. Rosario taught many classes. He puts together extensive lectures that give you most of everything you need to know. BIO110 isn't hard, test are online and anywhere you want. This builds for other classes though

BIO259 was the first time college really kicked in for work. Again, he always had good lecture slides and good information. You were able to watch the lectures back online, which was nice. I forget how the tests were but great teacher overall

Rosario is very clear, and uses real life examples to help you understand the material. This class really isnt difficult you just have to have motivation. You have to be willing to devote time to making flashcards, and use REPETITION for studying! Do a little each day, and make sure you understand in the moment what youre doing in class. Dont cram!

The lecture exams are very difficult. I was always very good at anatomy and his tests are not easy to study for. The way he explains the material in class could be a lot better. The test questions were weird, and the lecture slides had no information if you skipped class. Despite this, Professor Rosario is nice and truly cares.

Dr. Rosario was amazing. he explains things very thoroughly and genuinely cares about his students and wants us to do well. he gives extra credit when he thinks the class is struggling and asks students what he can do to help us. take him if you can! attendance is mandatory but all lectures and notes are on the class page.

I had Dr. Rosario last semester for BIO110 and just finished having him for BIO259, and I would have him for every semester if I could! His lectures are extremely informative and match up well with the exam content. If you show up to every lecture and take detailed notes, you will do well. Dr. Rosario made hard topics easy to comprehend. 100/10.

Dr. Rosario is one of the best lecture professors I have had! He is very nice and makes lectures engaging and easier to understand, the class average was on the lower side since he made the switch to in person exams but the exams aren't that hard if you pay attention He also gives out a lot of extra credit opportunities!

Dr. Rosario's amazing. People complain that the tests aren't online; they want to cheat. Sadly, you can't take exams in a lecture hall anymore without peers complaining to each other. Cheating discredits everything that professors do to ensure they provide good lectures. Dr. Rosario is excellent. Study hard, and you'll be good. Take no shortcuts.

Do not take this course if it's not required for your major or Gen ed. He just rants about information in the lecture slides when half of that info isn't even on the lecture exam. He also makes the lab exams and doesn't choose good bone and muscle models to use very confusing.

You will have 50 minutes to answer 50 questions on all 4 lecture exams. None of the material will be like the slides the questions are not definition based at all like the slides are. And they are open note but with that many questions you can't even look at your notes. So no point and they don't help.

the lab practicals are overly hard. spelling counts, no word bank, basically pointing to something and you have to know the spelling and what it is. have to study 100+ terms for only 25 questions is insanity. studied for WEEKS for the exams and failed all of them. didn't matter how much i studied, the tests trick you up. sucks bc he is a nice guy!

50 questions in 50 mins for all exams = very hard. You can have handwritten notes, but MUST know the material very well. The lectures are enjoyable and he knows what he is talking about. The exams test you at a college level when he explains it at a 1st grade level. Be sure to read the textbook and go to class. Attendance is included in your grade.

He is a good professor and cares about his students. He gives extra credit for the test if the overall grade is bad. The exams and final are open-book, which is helpful, but students will run out of time if they rely solely on notes. He considers our feedback and tries to improve. He also has optional review days before the exams

Professor Rosario is a great professor. The lectures are kind of useful, but definitely reread the slides and USE THE TEXTBOOK. He is very caring, responds fast, and gives lots of extra credit. Just make sure you understand the slides and the textbook and you should be good. He def isn't a hard grader, just make sure you study of you could do bad.

Very difficult class but great professor. His exams are not too difficult but you MUST read the textbooks and show up to every class. The lab and the lecture are hardly related, so it is basically taking two courses. If you don't study for lab you will fail. He is very accommodating and nice and makes things as easy as he can with a difficult topic

Very nice guy. Will answer any questions you have, and usually bumps exam grades. You must go to class and take notes. Although, sometimes the slides don't give enough detail. Looking in the textbook definitely helps as well. The only homework he gives is textbook assignments which are very easy. He always lets class out 5 mins early.

people say A&P 1 is really hard but it's not. Rosario is a great prof. Go to class, do all the homework, counts for a lot of grade. Using the study guides is literally the key. I filled them out and repeated them over and over and never got below an 80 on an exam. Just put the work in and you'll be fine, don't listen to these idiots on here :)
