He never comes to class prepared and his tests are pretty tricky because he tries to trick you. He does a bad job at explaining stuff because he just speaks math and just repeats what he said when you ask him questions. There are better profs than him at Rose.

Bleh is all I have to say. Makes calculus seem like a foreign language.

This guy is an D*** head he may have known what he was talking about but he treated people like they were very inferior and i hate him

not very helpful when asked question about how to use something on maple responce was look it up in help

WORST TEACHER AT ROSE! You can never miss class or be late. He yelled at a student for asking a question during class. Would frequently be unprepared have us do practice problems from the text instead of teaching us. Once asked for help, and he said "if you don't understand this then you're in sorry shape" and walked away.

terrible teacher. he thinks hes better than you and when you ask for help, he blows you off. also, 12 out of 20 people had to retake his class

Extremely smart but couldn't teach.

Worst prof ever. He didn't explain anything and wouldn't even help if you asked a question. He had in class work days and refused to help at all. He was rude and even scared me when I came to class. Never would even approach him outside of class because he made every one feel like an idiot.

I will never, ever have another class with this man again. He is by far the worst professor I have ever had in my life.

lectured almost everyday- terrible handwriting difficult to follow kinda funny--but weird his exams are from book questions so this is his only saving grace I think he is smart but he forgets this is our first go around and probably his 20th. Instead of making it easy for us to learn he is very challenging.

Do NOT take Leader. He is a decent human being but not the person you want making your tests and grading your tests. He makes his exams worth 95% of your grade while homework is only 5%. His exams are nearly impossible and will NOT curve them. My class average was a 62%. We also had over half the class fail or drop. DO NOT TAKE HIM!

He is a very smart professor who knows what he was teaching very thoroughly. However, he was not very helpful in explaining the content. During class, he would not take questions that interrupt his lecture, he could not explain things multiple ways, and did not help prepare for his tests which were not easy tests.

Extremely interesting lectures and extremely interesting guy, that being said he grades incredibly hard and inconsistent, its almost random. He wasn't very interested in the material either and it really showed. I am serious when I say half the class failed. He is also kind of mean if you ask dumb questions so if its not necessary to ask don't.

Did not care about students. Went off on random tangents almost every day about things that did not relate all to the subject at all.

The worst professor I have ever met. He teaches nothing (Don't have any videos or lectures for online classes and just let everyone teaches himself/herself !) and just email you homework and project stuff. He is a very lazy professor and please never take his class.

Dr. Leader does not lecture. He instead has you learn from either reading the textbook or from watching MIT Open Courseware lectures. Also, he has 1-2 quizzes every week, and has 2 mandatory groupwork meetings, where you and your partner work though problems, while he does nothing. Not horrible if you know the material, but literally doesn't teach.

Grader for this class... It's bad Homework is insane. In other classes, I get about 4 problems a day, due 3 days later. For this class? 7 problems a day, due at 5pm same day Lecture consistency? Not a thing. Sometimes it's "read the book", sometimes 2hrs of videos 50% of the grade is quizzes, and he'll dock 40% for algebra Don't take him please

Nothing about this class is good. If you want helpful lectures or anything helpful at all, don't take this class. Don't take this prof at all, for any class, if you want to learn anything and actually succeed. Homework is awful, get ready to do every single problem from the book with absolutely no guidance and no knowledge of how to do anything.

As a student who's had arguably some of the worst math profs at Rose, Dr. Leader is an EVEN WORSE professor. Exams were worth 95% of the grade for Calc III, and questions were nothing like the homework. If you fail his first exam, he even hands you a drop request. If you are stuck with him, good luck.

You quite literally learn more doing the homework than attending class, so you may as well not even show up to class and instead hammer the book into your head. It all doesn't matter though: if you get less than a 50% on the first exam, man LITERALLY hands you the form to drop the class. If you are bad at taking exams, do not take this class.

I would rather quit Rose-Hulman than take another class with Leader. This class's textbook was the only one I've read every word of, because you won't pass otherwise. Never teaches, only brags about how smart he is; lectures only made me more confused. Exams are impossible, homework is necessary to learn. Avoid at all costs, he needs fired ASAP.

Imagine the text-to-speech function on your Ebook but with some personality. You enroll in his class to hear him read off the book for 50 minutes then go on a tangent on how smart he was when he was your age. Hard grader and a bad teacher. Don't be fooled by his friendly demeanor. You are better off reading the textbook than sitting in his class.

Dr. Leader is the worst prof I've had at Rose. He does almost no example problems and his lectures consist of him reading from the textbook or going off on random tangents about himself. He doesn't care about his students and actually acts like he WANTS people to fail or drop his class. Save yourself, run away from him and his creepy uncle vibes.

By far and away the worst Prof I have had so far. His lectures are abysmal as he reads off of the textbook and goes on and on about how great of a mathematician he is. No help during his office hours and acts like he wants people to fail. The average on the first exam was so bad he refused to share the average and 95% of your grade are exams. AVOID

This class material was not that hard, but with this professor it made it 10x harder. His handwriting is near impossible to read. His grading on his test is very specific and you need to explain everything you did and get everything exactly correct for full credit. 1st exam average was 38%.

Easily the worst prof I've had at Rose. He doesn't do any actual teaching, forgot to give us the textbook, has horrendous grade weighting and has made multiple comments with sexual implications. His mind is so far gone that he thinks poor grades are all the student's fault, not his. May God have mercy on this man because my course eval will not.

To call Leader a teacher would be an insult to the hard working teachers at Rose. His "teaching" style was that of an audio book on 5x speed as he reads directly from the book and treats everything as review. He was truly the worst teacher I ever had and its very odd how his rating is so high on this website as over half my grade dropped/failed.

Jeff is terrible. Wasted so much of my time and made this course significantly harder than necessary. Please avoid if possible.

He's just bad; please avoid him at all costs.

Actually the worst prof at Rose. His lectures consist of just reading the book. He works through ZERO examples in class. He also writes tough exams and will take off points for the smallest things. Homework is worth a total of 2% of your grade so if you mess up on an exam you are screwed for the rest of the class. If I could give him a zero I would
