Reviews of professor Leoncio Quinones

Rating: 5.0/5, difficulty: 2.0/5
Really great professor. He wants everyone to pass. Spends a lot of time making concepts clear. Probably the only thing I would complain about is sometimes he shoots down questions about things he's already explained.

Leo is good! He has a thick Columbian accent so that is something to be aware of, but you get used to it. Unfortunately, he is not the best at answering questions (Instead of explaining it differently, he repeats what he already said). He sets up the class in such a way that if you put in the work, you will get a good grade!

Professor Quinones was an alright professor. I really liked Linear Algebra, and I think he pushed me to work harder in the class. I see some reviews stating that he said that you would fail on the first day. He did, but it seemed like he was joking. He, at least after some prompting, gave real world examples that helped to learn the material.

Tells you the first day he expects half the class to fail.

I had Leo for linear algebra last semester, and I'm glad I could have him again for diff-eq. He sets up the class in such a way where you have to work for your grade, but it's definitely attainable. He gives a lot of homework problems, then grades you on a few of them for quizzes and exams. I would definitely recommend him!

He is a very difficult grader, it is almost impossible to get 100% on assignments. To make up for this you have to do well on the tests which arent too hard. He is a terrible professor and admitted to failing the same class I was taking from him before he passed. He is awful at teaching and has low patience for questions.

The course material is not easy, but the work load wasn't huge, either. He's a good lecturer, but sometimes came across as abrasive (partially due to having English as his second language). Not horrible though. He writes down everything he says during lecture, which makes taking notes EASY (which is good). Easy pass if you take notes in class.

Terrible. The first day of class tells everyone that half of the class will fail. He probably doesn't understand what he is teaching, because he refuses to explain anything after he already talked about it once. Honestly, you're better just watching videos, as class sucks knowledge out of you, rather than learning anything. Harsh, but true.
