Wanted to like this since the professor seems like a nice guy, but this course is a glorified recitation & semi-abandoned. If you ever had a recitation were the instructor repeated the important proofs from the lecture, and laid out a few examples, this is what you can expect from this course.

Compare this course to lower level, equivalent level and higher level courses: As reference I will use Khan for (much) lower level, MIT for equiv. rigor (comparing intro to intro) and a much higher level course than these (I tested something in my language, Tehcniyon if you're interested) - The conclusion is that others do a good job giving you some storytelling that connects all the subjects nicely even at much higher levels. This course tries, but does not do it well, so it's not far from being an aggregation of subjects. Also like a recitation.

Exercises - there should be more, each DE kind is covered in only 1-3 exercises.

Organization and support - forums are dead, lessons are broken at quasi-logical points.

Challenge level is good - not trivial, but not too much for something you do for fun in your spare time.

I have enjoyed taking this course. The topics have been divided very well in that they are not too long and hard just the right amount. The lecturer was delightful and easy to understand.

Everything on the course is literally something i could find in a book. No additional comments by the professour. Boring.

The professor is just reading every thing. He doesn't even change his tone and says "key?" and "eight?" all the time as we could answer. That would be OK anyway, but he doesn't explain the theory, he just reads. I'll download a book from the Internet and study it, since no one else is dictating ODE in coursera.

I heartily thankful to Coursera team who helped me lot to complete this course and last but not least I would like to say thanks to Prof. K.H.Kwon.I have learned lot thorough this course .

coursera is best online platform to learning. i recommend every college school student to learn from coursera it's far better than your school and college teacher

This is a very good course ,It helps me to be an expert in the field of Ordinary differential equation

Thanks a lot to Coursera for to provide this course

Well structured course. It starts right with the basics and goes all the way to UG level toughness.

Buen curso, aunque la metodología debe involucrar didáctica con recursos.

Junk

First of all i would like to thank the University and the Professor in particular for the great labout and the brilliant opportunity they offered us to look into Ordinary Differential Equations. I really appreciate your efforts to make our worl better by stimulating us to know something at a high professional level. The explanations, the illustrative demonstartations of how it all works in reality has deffinitely deepened my understanding ODE. I wish you to organize the next logical course linked with differential equations. I will be one of the first students enrolled for the course. My best regars and sincere thanks to all of you: the Professor, the teaching staff, the University management from Uzbekistan.

My name is Dr Adnan Khan I'm from Pakistan. I want say that i have learn a lot from this course it was really very interesting course and it will help me in future when i will teach to my students again thanks a lot to Professor Hyun and Korea Advanced Institute of Science and Technology (KAIST) to manage such a great course and great professor. Hope so you will continue this struggle in future.

Dear Professor if you have more courses on Coursera then let me know i want study your more courses.

Best Regards

Dr Adnan Khan

I AM VERY HAPPY THAT I HAVE SUCCESSFULLY COMPLETED THIS COURSE.THIS COURSE IS VERY INTERESTING AND I LIKE IT VERY MUCH.THE WAY OF TEACHING IS VERY NICE.IT IS INN AN UNDERSTANDABLE MANNER. EVERYONE CAN EASILY SOLVE THE PROBLEMS BY UNDERSTANDING THE CONCEPT.I WOULD LIKE TO THANK COURSERA TEAM AND I WOULD LIKE TO SAYLIKE TO SAY MY SAY MY THANKS TO INSTRUCTOR Kwon, Kil Hyun.

I am sincerely thankful to your Generous courses on ordinary differential equation。 As a student from China, I have learned some basic knowledge about it In our advanced math class. However, this class give me a marvelous opportunity to get a deeper insight about it. It helps me to have a comprehensive perspective about it

Suitable concepts about ordinary differential equations and its concepts , with a little touch of applications just like pendulum, spring mass system.Especially, the lectures were well explained.I really very much happy to be as a learner of this course.

Overall the course on Introduction to Ordinary Differential Equations is good. I recapitulated my basic knowledge on ODE. Now I would like to learn advanced level courses in this area of Mathematics. Thanks to Prof. Kwon Kil Hyun.

MUY BUEN CURSO PARA APRENDER ACERCA DE LAS ECUACIONES DIFERENCIALES YA QUE TE BRINDA UNA INTRODUCCIÓN A ELLAS Y APARTE TE MUESTRA SU UTILIDAD EN LA VIDA REAL, LO RECOMIENDO MUCHO ES BASTANTE BUENO ESTE CURSO APRENDERÁS MUCHO

Great work! now i have knowledge about differential equation after completions of this course. i learned some basic concept related to differential equations and also physical meaning of differential equations.

The course is correctly paced. The lectures are extremely good and carries lots of details. Overall, the course is very well organized, extremely thankful to the instructor and others for the support.

Really very interesting. Weekend so no other work than doing courses. Thank you so much for offering the chance to do some courses in coursera. Thank you

This course of Introduction to Ordinary Differential Equations was very interesting, I enjoyed it and I learned what I need to expand my Knowledge

A very useful lesson for those students wanting to take a step further than AP/ALevel and freshmen that are struggling with math classes.

It's a really amazing course. Really glad that I take. Some of the video has little sound, but overall it's really good and clear.

Really learnt alot from this course specially application part. Thanks for your support. Really very hard working instructor.

It is very informational to all of us students regarding differential equations and its properties. thank you
