the pretest reviews bluntly tell exactly what is on the tests

More conceptual than practical, hard tests, but very enthusiastic/interesting

He is hard...but he is nice and helpful, and motivated about math, Good Teacher

he is boring but he constantly reviews what he has already taught and moves at a good pace not too fast or slow. he is always willing to help you and wants everyone to suceed. and he tells you exactly what you will be tested on.

The nicest man ever. So helpful. Explained a whole lecture that I had to miss later, in his office. Tons of extra credit "quizes." I hate math, but I loved the ancient geometry we learned. He explains everything in great detail. Gets passio

Great teacher, outlines notes well. Good explanations and nice guy overall

marafino is a cool guy. he gives lots of extra credit if you do your homework, enough to give you an A on a test if you didn't take it.

Marafino has offered over 80 extra credit points this semester with more to come and the class is only out of 500 points, so that is like 15 points added on to your final grade. Outlines tests nicely, and has an easy grading scale...40 for a D, 60 for C.

One of the best professor I've ever had. Lectures are clear and descriptive. He truly wants you to succeed and gives you the opportunity. He makes a class that most would consider booring, funny and lively. I wish all professors were like him.

Marafino knows the course but not how to teach it. He only has 3 tests and a final. You basically have to teach yourself the material. He teaches different than the textbook.

Let's just put it this way...1/2 our class dropped out. No curves...a really nice and smart man, and willing to help, but just has trouble teaching material well.

I wouldn't recommend this if you haven't had a calc class before. But he is a great teacher and really knows his stuff. If you don't understand something, he'll make sure you know it before he moves on. Tests can be hard, but he takes the questions directly from homework. Not too bad of a class.

Dr. M is one of the best math professors I've ever had. Don't listen to the Math 205 people, they just were forced to take the class and already despise Math. He makes it easy to succeed in his class, study his outlines (its the test w/o the numbers), come to class, and do the HW for extra credit.

Good teacher, goes really fast though and assigns billions of questions for hw. Plus how interesting can calculus really be?

I don't like maths,but I like him.If u talk more with him,he's a nice guy.He give tons of extra credits if u do his homework correctly.If u don't do the HW,don't show up in class,it's not wierd u got a D or F.Strongly reconmmand for Asian students.He is the only maths teacher who gives me a lot helps.

He gets really excited about the material... In class he goes over why you solve the problems not nearly enough about HOW to solve the problems. nice guy, hell help you if you go see him during his office hours. Class is going to be difficult, gives a good outline of the test. GO TO WILSON CENTER!! it saved me.

Super nice guy! Always willing to help, all you have to do is ask! Do your homework for extra credit and GO TO CLASS! Tests are made up of examples from class and homework! Make sure you know the test outline!

The best math professor I've ever had. His class is hard but he makes every effort to help students in and out of class. He always makes sure you know his office hours and will arrange ones just for you at the drop of a hat. However, the class is hard, but his homework policy is great, for every problem right, counts as bonus points on tests!!!

Great professor! Such a nice guy, gives take-homes and mad extra credit.

Dr. Marifino is awesome! I think that is policy is completely fair, the extra credit encourages you to do your homework while helping you on the tests at the same time. Dont listen to the rating from the people in Math 205, they are just mad that they actually had to think in their class.

not a bad teacher. class is fairly easy compared to 236, its just the application of previous concepts in 3D. he makes hw extra credit, 3 tests during the year, and a final. gives study guides with exactly what's on each test/final (question by question). only down side is, he doesnt give +/- grades, so a b+ is definately a b, and maybe even the a-

Best math professor at JMU! Brilliant and incredibly warm and kind. Gives tons of extra credit and an explicit outline of each problem that will be on the test. He really couldn't make it any easier. Even so, you will learn a lot from him.

Professor Marafino is what you make of him. If you ignore the class, don't attend, and don't do the homework, you will not do well. He can sometimes be a little confusing, and often sounds like Christopher Walken, but if you seek help, ask questions, and are willing to do the work, you will succeed in this class.

His class was not too difficult if you are willing to put time and effort into it. He offers a lot of extra credit points by collecting the homework. Also, his exams were fair by putting questions from the homework on them. If you do your hw, you will earn a good grade for the semester.

don't be intimidated by the first day of class. If you pay attention and do the homework, you will get at least a B. His homework is extra credit and he pulls homework questions that he grades and puts them on the test. i have no idea why ppl would say he is a bad teacher when he isn't!

He's a god professor. Very funny. I think most people are looking for an easy calculus class, but those don't really exist unless you're naturally gifted at math. He is very helpful if you just ask questions. Gets very passionate about the subject. I wanted to take 236 from him next semester, but he isn't teaching it.

Great guy, Great teacher. Handwriting is pretty bad, but other than that he is a good teacher. You will get what you put into this class. Do all your homework and you will be fine. He gives you an outline of exactly what will be on the tests. You get get about 1/4 of your grade in extra credit also.

Marafino is an awesome teacher and a great guy. The effort you put into the class will show. Do the homework and go to class and you will do fine. Homework is extra credit, and he has a great system about adding it to your final grade. Gives you an outline of the test, so there is no surprises. Also he is extremely helpful during office hours.

Best math teacher I've ever had. Calc is never going to be easy, but he explains things really well and is a big help in office hours. You get an outline for each exam, so studying is a breeze. Do your homework because he gives you a point on your test for each problem you get right that he collects. I got 50 ec pts. Do the hw, go to class, easy A.

calc III is a hard class no getting around it. Marafino's teaching style is you learn it on your own then come to class and review/refine what you learned. Lots of independent book work needs to be done. There are easier teachers than him to take for this course. Overall i don't recommend him, he's poor but not horrible.

He's a pretty goofy guy but his teaching style is pretty clear and tells you what he wants. Follow the rubric for lab reports and pay attention to his lectures, he'll emphasize test materials. Really understand the labs where you have to identify things for practicals. Tough testsquizzes but nothing you can't really study for.

Can't believe I'm about to say this, but he actually made BIO lab fun (sometimes). It's not an easy class, but an A is 100% achievable. Always willing to help, and is very flexible. Strongly recommend him.

John Marafino seems to be a very smart guy and really interested about the subject. He doesn't give a calendar which can be really annoying but is good about making assignments clear.

Fantastic teacher. Is great at explaining all the concepts and really wants you to understand all of the material. Has a great sense of humor and his lectures during lab are always entertaining though his tests are often tough. Overall, fantastic, could not think of a better person to have taken lab with.

He is super laid back. He doesn't really reply to emails so beware of that. I really enjoyed lab with him. He explains concepts thoroughly and makes sure everyone is on the same page with him. He tells you what you need to know for the test will help you through lab if you're having problems. He is very approachable and I definitely recommend him.

People need to understand that this is college level calculus, there isn't a single teacher at JMU that is going to hand out A's for calc, you need to work for it. Take Marafino for his test study guides and partial credit. His study guides will show you the exact types of problems to look for and the partial credit will keep your grade up.

Great teacher, he's so passionate about everything math related and it shows through in his teaching. Quizzes aren't too bad if you study for them and go to his office hours. Pretty lenient grader if you ask me; on two quizzes I got 16/12. He drops the lowest quiz scores you get and averages the rest. If I get the chance to take him again, I will.

Genetics lab sucks, but Marafino makes it fun. He does his best to help, though he can get mixed up sometimes, so be patient with him. He tells you exactly what he's looking for in reports and presentations, and he breaks projects down so that you can understand them.

if you havent taken any calc courses before i would not recommend him because his lectures are confusing but I found the class easy because he gives you a mock test before every test that is identical to the test just with slightly different numbers. Also if you show all your work and at least set up the problems right, he gives you points.

John makes calc seem like a walk in the park to be honest.

Marafino is the bestttt. I would take him again in a heartbeat. He reminds me of Jack Black every time I see him. He's a super funny guy and cares about his profession and knows what he is talking about. He does tend to grade tests in an untimely manner, but other than that his class is engaging and its not the typically bio class.

Marafino has a gift! When I first saw his ratings they were pretty low. I discovered that his ratings didn't give him justice. He always makes class fun and is always willing to help you if you need it. He is also very personable. You will definitely need to put in work but he makes it worth it. He has been one of my favorite professors at JMU.

Good man, but a very difficult course for me personally. Honestly, im just happy I passed. He's easy to get a hold of via email, and will work with you. I would not suggest this class unless you have a strong background in math. Other people in the class who had taken calc in high school thought this course was a breeze. Your grade is 3 tests.

EXTREMELY passionate about Biology. Uses a lot of expression in lectures. Content is heavily textbook based. Available for office hours during the week but not weekends. Super open to feedback on course content. Doesn't check email on weekends. Very helpful during the COVID-19 crisis.

Your grade is determined by 3 tests. Dr. Marafino gives mock tests a week in advance which are extremely similar to the actual tests. The hw is optional. As long as you understand the mock tests you will be fine. Don't take this class if you don't have a strong math background. He will answer any math questions you have. Lots of outside learning
