Jenne is a great intructor, very helpful, and easy to talk to. The subject matter is very hard but he really wants everybody to understand the material. Do your homework every night. He gives out a handout before each test as homework to help you study for each test. Four tests and a final. He gives out one handout for extra credit.

Ralph was very friendly, very easy to understand, and very willing to adjust the speed of his teaching to the needs of the class. His homework was fairly easy, and I really liked his teaching style. He is VERY laid back and easygoing, and grades fairly easy if you do all the work. He gives 5 tests & a Final, and drops the lowest test.

The hmk from the book will not prepare you well for exams, but Jenne has a website where he has posted old exams. His exams will be similiar just different #'s. Practice these over & over and you will do well in the class. He is laid back unless your cell phone rings in his presence - it really upsets him! Not welcoming @ his office for questions

jenne is a nice person... generally he answers all your questions and explain it really clear. DON'T BUY THE BOOK...you will never use it. study his previous test the day before the exam and you'll be fine. he won't give you anything new.

He is really good at explaining everything and he loves answering questions, He has a great since of humor and always makes jokes about everything. He is extreamly knowlagable about the subject material and he s one of the easyest math teachers I have ever had to follow him along in his lectures, If you like math you will like him!

He is an ok teacher, HW grades are good if you do most of the problems. Tests are hard but short, and graded loosly. Lectures are sometimes off track, but with the book it's ok. Has a sense of humor, grins throughout the period.

good teacher, tests can be tough, sometimes examples don't really relate to the material (not alot though), I recommend this teacher but you'll definetly have to put forth an effort.

He is a great teacher! He has a subtle wit that keeps the class laughing while learning calculus! He posts archived tests, if you can master these you will master the class! Always willing to help and devotes a lot of class time to homework questions and archived test questions to prepare for exams.

Favorite teacher ever. I still hate math but can understand it now. An asset to north

Hilarious teacher. Makes you laugh while learning math. He knows the subject well and expects you to study a great deal on your own. Exams and homework are tough.

I thought he was the best math prof at NSCC. Helpful, fun and interesting. When i attended of course...

Great prof if you always show up, and do the hw. You will most likely be lost otherwise. He has a great teaching style that is organized and starts with the basics of each topic. Then, his class examples put everything into context what you've learned. I took him for 116 and 117. Great class. One of my favorites at North.

Ralph Jenne is a mathemagician and he carries with him a magical wand which he uses frequently to summon corny one-liners during his lectures. He assigned us no homework at all, and all of the points we earned were from 3 tests and a final, which is brutal. His charisma and charm are disguises for his sadistic grading style. I highly recommend him.

I think he is a great teacher who is very helpful. He is willing to work with you if you need it.

Very good teacher. Sometimes He chooses an angle that is a bit more complicated than others (ie: teaching trig starting from triangles instead of circles) but overall very helpful and nice. Grading system is good, depends on the tests. Fair in my opinion.

His test are extremely hard, it has nothing to do with the material he teaches. Is very helpful but only goes over a new material during the last 15 mins of class yet expects us to know everything by the next day. The hw exercise problems issued were no help, and even the people at the math lab agreed his hw wksht passed out were difficult.

I really liked the class structure - 3 mid terms, 1 cumulative final and like 3 hw handouts. He has old exams and solutions posted online so you know what to expect. He also proved to be willing to work with students.

Ralph is a very good teacher but he has an extremely hard class. There is almost no homework and your grade depends on 5 tests. I still learned a lot but i got a 3.5. I would not recommend him if your GPA is important to you.

Favorite teacher ever. He is very helpful and fun. Very little homework and grade depends on 5tests. Highly recommend...

Very nice teacher. He's often late to class though. He explains things well and gives fun facts about math. Your grades depends completely on your quizzes and test but he goes over everything in class so there's nothing surprising at all. Great teacher :)

I think he is really Fair. He will help you if you have any question, and he will review all stuff before test. You will get good score if you study hard.

I was dreading taking math again after 11 years since College Algebra, but he makes the class fun and interesting. Kindof a goofy guy, makes a lot of jokes, which really helps get through a 2.5 hour evening class. More than fair grading scale and gives great explanations as well as being very available for office hours extra help. Highly recommend!

Ralph is a great teacher that makes a somewhat dull subject remarkably entertaining. He is the king of corny one-liner comedy and will constantly have you chuckling. Tests are fair and follow the homework recommendations from the text. Relaxed, laid back class, and great for those who prefer to study on their own. Highly recommended.

Ralph is full of humor and is a great prof. A changing work schedule caused me to miss a majority of the classes at night except for test nights and I regret not being able to experience more of his lectures. Self studying linear just wasn't as fun as being in class with him and his witty jokes. Highly recommended!

Two thumbs up. Jugding by the completeness of his answers/explanations, Mister Jenne's level of expertise is very high. Good sense of humor. Grade based on quizzes/tests only, and no curve, which may be rough. If you like math, great teacher. If you don't, dunno... lots of comments below about his being unclear/etc, but I didn't get that at all.

Ralph is a very understanding and fair instructor. Not only does he know his stuff...but he's also funny and engaging. He will go over as many HW problems that students ask of him. Ralph helped me out when I was struggling, I will never forget him. If your generally good in math I urge you to take Ralph Jenne...

He's not as awesome as Hon Li, but it was still a great class. The lectures are pretty interesting, at least for Diff EQ, and he's good about answering people questions.

Ralph is a helpful teacher, and he kept the lectures interesting (or attempts to keep them interesting). I couldn't take notes fast enough to keep up with him at times. He would sometimes make simplifications on the fly that made it unclear as to what he had done, but that was not often. He was very willing to do many sample problems.

He's a really good professor. He explains the materials clearly and he will go through some homework problems. His quizzes and tests are easy n he has a good sense of humor too. Take his class!

Great teacher! Easygoing, friendly, helpful and smart!

I thought Ralph was a great teacher. I have heard others at school complain about his methods(too fast, not cohesive) but the pattern was that those people really had a hard time understanding math. If you have a fairly decent grasp of math and do not need your hand held, then take his class. He makes it pretty entertaining too!

One of the best math teachers I have ever had. Makes it easy to understand complicated items. One tip - DO THE HOMEWORK (even if it isn't mandatory, it only helps you)

He's not that hard of a professor. He doesn't require his homework and it's just up to you to keep up. He's actually quite clear in class, and responds to questions well. He does move fast, but I think that's the structuring of quarter system, not the class itself. Willing and going to take his Math 141 class.

Ralph was great! I took this as my college level math requirement. This one quarter of math made more sense to me than three quarters of remedial algebra ever did! Math 107 has real world application, so I suppose that was why I understood it. Ralph is kind, patient, and will go over material until the class gets it. I recommended him!

He's a really nice guy--funny too. But the course is disorganized and he teaches from the top his head. You'll understand the stuff that he does teach, but you'll definitely have gaps in knowledge. I ended up using open source sites and videos to get me through numerical analysis. His tests are easy though.

Ralph helps students a lot. If you have any questions about math from algebra to a complicated calculus, he is glad to help you. However, his teaching style sometimes is boring. But, overall, this class is great for me.

excellent instructor. Very funny during lectures (if you listen - dry sense of humor) and I never once saw him act annoyed by questions (even when I was sometimes annoyed that students were asking him to repeat info). He is approachable and kind and smart. I hope to take another math class from him in the future.

He came in and sort of rambled through lectures, but he seemed to cover everything necessary to pass his class. The tests and assignments were pretty easy, although sometimes they could have been more clear. Very nice guy and was always willing to help anyone through their issues.

I took two courses with Jenne.R (MATH220 & MATH 146). I felt that these course was great. I learned a lot. I would definitely suggest others take from him. He knows the subject matter very well, explained very well, is very enthusiastic about teaching, cares about students progress, and willing to explain problems and provide applicable examples.

Ralph Jenne was an amazing teacher. I learned from him. His notes tend to messy but if you can sit in the front and actively engage, you are good.

He is an amazing teacher if you are willing to study hard. He has very solid knowledge. He can help you outside the class by explaining thing that you are stuck on. One thing that I wanna complain is his hand writing is so bad so you should sit in the front row. His exam is based on his lecture.

One of the best teacher I have had.

Great teacher in my opinion. As others have stated, he isn't very organized with his lesson plan; however, everything he quizzes and tests you on is based on the assigned homework (which is also assigned in reasonable amounts and is not overwhelming). He'll answer any questions in class and does a pretty good job with his examples and explanations

Very good teacher. Doesn't give a ton of homework and his test and quizzes come directly from the homework. Don't miss any classes however because the class is a little fast paced. Also very hilarious his anecdotes have had me in stitches a few times.

The homework is custom made by Ralph, and did an excellent job of showing me where I was strong or weak on the material. I never had a test result that was a surprise to me. I also found him to be very helpful during office visits as he is very capable of explaining a concept in more than one way, which allows him to teach to my learning style.

ASK FOR HELP IF YOU NEED IT!!!!! Also the homework is hard! But Test less so. DO the optional homework and you'll do very well in this class.

I LOVE him. He's the math person for people who suck at math.

It's not easy to get a 4.0 in his class because he never gives us chances for extra credits. But I have to say he is a good teacher. He explains topics with lots of sample problems, which are very similar with the problem in homework and quiz.

He is one of the best math teachers I had, and by far he is. I had him for Math 141 and he didn't use the book, but he showed the class many examples and with good detail. He is funny all through class, so its always a fun class to go to.

minimal hw (but content is a good indicator of what will be on the test/quiz), tests are totally manageable if you show up every day. He has his own website instead of canvas, and labels something as "book homework" in his syllabus that should be labeled "optional practice problems" because that's what they are. Just do the hw he passes out.

TOUGH GRADER!!!!!!

Ralph is a fantastic teacher; he is very knowledgeable and passionate about math. He encourages students to think out of the box and gives challenging homework which you can get help with. His tests are very easy, if and only if, you do the assigned homework which are very few. I highly recommend him, especially for engineering students.

My favorite math teacher at NS. -Allows calculator -De-emphasises memorization -Emphasiszes application He has two kinds of HW, graded and ungraded. His ungraded HW is his greatest strength. Well chosen exercises practically teach themselves, very helpful. Graded HW and tests emphasize theory and application. Do the ungraded HW!

I will recommend this class to all those who's passionate in math. I had a lot of fun discussing math-related topics to Ralph in his office and as someone who loves math, he can be very inspirational. I cannot say much for those who do not share this, though. The theme of math advice is the same: don't memorize, visualize. Especially in this class.

Ralph is amazing, he is kind of quirky and some people don't like him because of that but if you already have a passion for math he is a great teacher! In his calculus lectures he brings in a lot of physics and expects a certain level of physics understanding but if you have taken a basic physics class you should be ok.

All assignments are published up front so you can work at your own pace (there are due dates, though, but you have the ability to progress ahead of the class). Tests are challenging but not unfair - show your work to receive partial credit on questions you can't completely answer. Also had them for 141. Prepare to work and expect to learn.

Professor Jenne is such a great teacher. He's always willing to answer any of your questions. He always gives extensions if you did not have the chance to finish the homework on time. He's very knowledgeable about precalculus. He also teaches the class with lots of examples, so you are ready for the exam. Pretty good teacher 10/10

Ralph is a fantastic professor with a genuine love for math. Hope to take another class with him. Workload was manageable and tests were tough but fair.

It's my first time studying in an American college, and Mr. Ralph has always been a great person to work with. Although my grades aren't that good, he is a great guy in his lectures, and I hope that everyone in his class takes it seriously. The workload is not that much, but the tests are very heavy. Good luck!
