I took the class with the commenter below me. As long as you pay attention, do the homework, study outside of class, you will get a good gade. The commenter below me was immature, asked the dumbest questions, didn't raise her hand and just pissed people off. Dedinsky is a good math teacher. You just have to be willing to learn.

Absolutely brutal. Takes time for questions, but answers in a roundabout way that leaves you even more confused. Seems to be more interested in personal stories than actually teaching. Basically demands you learn logically; bristles if you prefer an alternate method. Made so many mistakes the class was forced to check him each step of an example.

This guy is boring. Bored me to tears. The only thing more boring than the math are his lame anecdotes. He is a clear teacher, he paces the class way too slow, and he gives easy tests. Before each test is a helpful study guide that has similar questions to everything on the real test. This class is easy. His smile is creepy. Real creepy.

He is hard. Doesn't give problems from the book. Makes his own homework problems which are the tricky ones. You have to attend class or you won't know what the homework is. Grades your homework from 2,1, or 0. I don't doubt that hes not smart its just that he is not good at explaining it. If you are bad at math I don't think you should take him.

Textbook is never used. Exams are based on his homework problems. Sometimes, they are even identical to the homework. Teaching style is a little bit hard to understand because he skips a lot of steps to get to the final answer. He gives "liberal" curves on the test, so again, just learn to do his homework problems and you'll pass.

Well, Professor Dedinsky is one of the greatest professor I ever had. I took Calculus course (Math 3A) with him and I love the course but his teaching methodology was poor. He didn't write word problems on the board. He only imagined & drew it so, it's pretty hard to understand the concept by yourself. But, he is an easy guy and fair in grading too

Mr. Dedinsky is a phenomenal professor because he's can be flexible if students have questions on homework. He doesn't mind answering questions. He's respectful of students' questions and is open.

I'll be upfront..if Math is your thing, then you will really enjoy this teacher. If it isn't, and in order to understand the material, you need to do homework with numbers instead of proofs, then try enrolling with another teacher, chances are you will be struggling. It really depends on how comfortable you are with Math and your learning style.

I took his Calculus 1 in spring 2019. This class is not difficult if you really pay attention and do a daily work. He let you know ahead potential questions in daily Quiz and Midterm/ Final. He grades easy, but no extra credit. Midterm 1 and Final is manageable, midterm 2 is the hardest test in an entire semester.

Good professor. Easy if u put in the time and effort. His notes are sometimes difficult but he marks the potential questions, so it's a fair game. He's really sweet and helpful. 2 midterm, a final and daily quizzes and he tells the quiz question.

He makes more mistakes than most teachers and he expects his students to find his mistakes even though we're busy trying to learn what he's teaching us. His handwriting is very sloppy so it can be hard to understand some of his notes and my last complaint is that he only posts notes on canvas, I can't even see what my grade is for his class online.

Spends most of class time doing problems on the projector and then he publishes them online, although his handwriting is very difficult to read and he skips important steps, so you need to attend class. He assumes you have a strong math background. Study by practicing the marked test questions. Pro tip: Make a summary sheet of each concept to study

Johns math classes are formatted weirdly comparing to the other math teachers. Instead of showing us applications, he gets to focused on theorems. The way he teaches the material does not make sense. If you are good at memorizing. U should be fine with him. If not good at memorizing, then it will be tough.

Prof. Dedinsky is amazing! He tells you all of the potential test questions beforehand and is true to his word. There's no homework, only practicing the 50+ potential test problems. He curves his tests (most of the time it benefits the class average) and also has extra credit too. Just make sure to do practice the problems he gives you. Easy A!

I took his 3B class, the material was really hard especially the midterm 2 and final. However, he spent time to explain and made sure your questions answered. In my class, he caught few cheaters, so if you tried to cheat on his test. Enter as your own risked. Make sure you spend enough time to understand his materials and concepts. Asking is a key

I only decided to take his class because of his decent rating: bad idea. Unable to explain trivial concepts simply; it always has to be long drawn out proofs. The majority of your learning will be done on your own time. Ridiculously hard test questions. Like someone said here before, it's learning knitting without any pictures; there are 0 visuals.

Dedinsky is the best prof for people that have a decent math base. He has a 200 page document of questions for the course that he slowly works through in lecture and he teaches you everything from that. Study off of his marked test questions on the document and you'll get an A. Exams are extremely fair and super short and easy.

Exams often had nothing to do with the homework he gave but instead tested you on a few basic skills and a proof for something a skill which he gives no guidance on how to go about. Test material is Unclear he gives you concepts but nothing to get an idea of how it will look on the test, he doesn't do review sessions and instead moves ahead.

VERY theory based. Be prepared to memorize theorems and proofs. Not very interactive with students during lectures. Approachable enough but doesn't really help. Little to no homework but all of your studying should be on memorizing theorems and examples he labels as 'potential test questions'. Exam problems are tweaked test questions, or verbatim.

If you ever wonder what it feels like to be completely lost despite paying attention to lectures, hes the professor that will give you that exact feeling. Lectures were not just heavy but it was too much information to take at a time. Gets way too focused on theorems rather than actual math. Id highly encourage you to avoid taking him.

He is very passionate and knowledgeable. He teaches using a 200 page document with various problems. Some of these questions are marked as potential test questions, so the test questions are directly from the lecture. Ask if you don't understand something; he explains very clearly. Pay attention in class, try your best, and practice makes perfect!

dedinsky marks what's going to be on the test. even though majority of the test questions he marks are theorems, as long as you understand what's going on in the theorems and memorize them, you should be fine. what if you aren't good at memorizing? well, put in some work memorizing those theorems. for linear algebra, they're pretty hefty.

His lectures were boring to sit through because there wasn't really any enthusiasm behind his voice. However, everything is about memorization. There are 10 questions on each test (3 tests total + are curved) and of the 10 you will see in the lectures. If you can review 30 minutes a day it should be a cake walk...

I took this class for dual enrollment, he tells you exactly what's going to be on each midterm and final so its very easy to study for it, if you put in like 4 hours before each test its possible to get a 100%, he curves the midterms very generously (for one of them a 68% was a B), and there's barely any homework and all the homework is optional.

Wide amount of exams adding up to 60% on your grade, eg 2 exams, each worth 30% (up to 6 exams). I had 2 exams before the final, they'll mess ur grade if u dont do well. Practice given problems multiple times AND learn the concepts. He often skips over important steps in class bc too "trivial." Hw's worth nothing. Very passionate abt math tho

I took his MAT-003A course just to solve the problems related to limits, derivatives, and integrals. He was an okay prof, to be honest, but his way of proving the theorems step-by-step was a complete nightmare for me, as well as hearing "this is something you should know". In addition, during lectures, his handwriting was difficult to read.

He uses a 170pg document for notes. Not a lot of HW is assigned, but he marks a lot of class examples as "potential test questions" to be solved. Yes, he puts a fair amount of them on the test for the given chapters, often verbatim, but proofs are usually included. Tests are curved nicely (73% = B).

He expects you to understand or practice ~60 pages per exam and he will put about 10-20 of them (marked as 10 questions with parts [a.] and [b.]). Curves are pretty large (70% = B), (~80%=A). Expect 2-3 tests to determine your grade. You get to know all questions beforehand as they appear on the exam. He's great and motivated -- just don't be lazy.

Professor Dedinsky is great—no homework, just pay attention in class. He clearly explains a 150-page doc and selects 10 key questions from 60 possible test question on the exams., some tough but manageable. Two drill tests are reviewed step by step. If you stay focused, the class is very doable and well-organized. Highly recommended.

This professor is good only if you have great memory and are willing to devote all your spare time to this class. His style of teaching makes you throw logic out the window and memorize page long proofs for problems instead. He also grades only based on tests, and his tests are incredibly difficult, as you try in vain to remember steps for proofs.

Prof. Dedinsky is great! The key is to practice the test questions he marks during lectures on a weekly basis and build fluency. He can move a bit fast during lectures, but honestly if you get lost don't be shy to ask questions, he does his best to help out. The tests are all curved and he gives partial credit. Don't slack off and you'll be fine!

Good professor if you want to get an easy A. Text questions are given in advance and the test is announced two weeks before the exam, so you have time to go over the material.

A few good things about this class are that the professor is actually really nice and he never assigns us homework/quizzes for any class day. Otherwise, avoid this class if you don't like memorization since we always had to memorize so many notes written in order to prepare and get good grades on the exams.
