they need to hire someone to enhance to user experience and UI ALSO better structure for the final pilot assignment other than that everything is wonderful

Great course, well tailored assignements and problem set. Once solved it gives the learner the confidence and knowledge to learn any math related subject.

Fantastic course! The lessons are clear and interesting and the forum is active.

The last week is much harder than the other but the satisfaction is high!

Very useful for knowing the basics of number theory and to think mathematically. Slow and Steady wins the race! Concepts explained with good explanation.

Excellent teaching style!! Will aid anyone to understand mathematical thinking!! Definitely take this course if you are taking mathematics in university

Wonderful Course. A great distraction from the Covid19 virus. Much more interesting and exciting than Netflix. Thankyou to all involved in its creation.

The content is great, well explained; and If you invest some time in it, surely it will open a hole new way to see Maths. Thanks for the good content.

It's a pretty good course. I learnt a lot. I hope Stanford open more math courses in math field, such as Number Theory, Analysis, and Abstract Algebra.

Excelent Course. We can learning more about math,even if you are a professional in the field of mathematics, for example, in the field of engineering.

Es un curso muy bien orientado, y el método de enseñanza es excelente. El profesor te enseña a pensar más allá, lo recomiendo para todos los niveles.

Thanks to Prof. Keith Devlin. This course is a must for everyone planning to undertake an undergraduate program in any field related to mathematics.

很棒的数学课程，适合大学新生在上高等数学时学习。这门课详细介绍了数学证明的方法，并且会告你大学学的数学和高中时不一样，最后一周的互评作业也很有意思，通过批改其他学生的作业我也学到了更多知识。这门课让我对数学有了更大的兴趣，如果你对数学感兴趣或者想学好大学数学的话，你应该来试一下这门课程！

Amazing subject with excellency in explaining. Widens our thinking process over the subject & general life. Loved that I finished this course.

You don't learn math only; you learn the techniques of logical reasoning.

This course is evaluable and helps me become a more effective thinker.

Such a delight having followed this course... it was a real pleasure to think differently other than usual... thinking mathematical for once...

Τhe lecturer of the course is quite explanatory. The course material is quite well organized with methodical steps in explaining the concepts.

Great lectures that broke down intimidating concepts to be understood easily. I already feel the impact on my thinking. Thank you Professor!

curso muy bueno, muy desafiante para el pensamiento y para cambiar la perspectiva de lo que ya tenemos aprendido previamente. recomendable.

very good course to learn mathematical reasoning. You miss many important points when you are a graduate and have lot of material to study.

I'm from Indonesia. This course is very good. I think this course is great for those who want to understand how mathematical proofs work.

Considering the world and media's regressive subjectivity, this course will realign your mental spine with some good old-fashioned Reason.

Dr. Devlin is very passionate about mathematics and it comes through in his teaching. This is a great course overall and very challenging.

It is a nice course to learn how mathematicians write proofs. Also how to think in logical way. Great course for maths enthusiasts like me

recommended to anyone who wants to seriously start discovering this fascinating world. Mathematics is the distillation of human knowledge

The course had generally taught me things that are not mathematics but the fundamentals of it and I like that is more important overall.
