Exceptional quality. I used to programming in haskell and thinks that it will be easy ride without new information. But there is many intereting topics like type checking (great home work to write simple type checker), modules and advanced pattern matching. Thanks, Dan.

One of the best CS courses available, if not the best. It enlightened me more on many functional programming idioms and concepts than any other book / course. However, this course is definitely not for total beginners, prior basic experience with programming is required.

Fantastic course and an impressive teacher. I've mostly worked with Python and JavaScript, so it was great to see a different approach to programming. The emphasis on recursion and currying was tough for a while, but there was plenty of practice in the homeworks!

I watch the video lectures as supplements for a course I am taking at my university, which happens to be based on this course. I feel compelled to say that this is one of the best courses I have ever taken and Dan Grossman is the best instructor I have ever had.

I wanted a friendly introduction to the ML language family and got a lot out of this. This is the languages course I wish I had in undergrad. I found Standard ML really enjoyable to work with and appreciated the focus of the course material. Highly recommended.

One of the best courses in which I've participated. Additionaly along with Tim Roughgarden my favourite professor as far as my familiarity with coursera and other mooc sites is concerned. Love to see his passion to the subject and become "infected" with it :)

This is a great course for any programmer. It delves more on how things work in programming languages why they are like that, rather than how to do things using programming languages. It does require dedication and the exercises and assignments are not easy.

Awesome course for anyone who likes programming. I learned a lot, and is helping me write better code in any language. Very thoughtfully planned, meticulous execution for videos, lecture notes, homework assignments. I enjoyed peer-reviewing fellow students.

Excellent course. At first, it felt quite challenging. But, once the material started to settle in my mind everything began to make sense. Professor Grossman does an outstanding job explaining things from basic principles and building up to larger concepts.

Maybe the best course I've ever taken in my whole life. If you want to learn more about functional programming this is the course you're looking for. The videos and exercises are very explanatory and will give you a deep understanding about all the topics.

Absolutely loved this course - lectures are wonderful, professor is knowledgeable, clear, and concise. I did not have previous experience in functional programming so I found the material quite hard, but therefore all the more challenging and interesting.

With this course I realised that functional programming is not just a hype or a trend. I really became invested in this way of thinking. The course is great, Dan is a great instructor and even more important is that the mentors are doing an excellent job!

Absolutely mind-blowing course. This is a must do specialization for anyone who in interested in Programming in general. Can't thank enough Prof Dan for putting this together. I really really really wish he does a complete specialization on Haskell now.

Excellent course. Best of all I've studied here. An interesting presentation of the material, well-planned homework. Also got a great motivation :) And, I hope I became a better programmer than I was :)

I will be glad to continue my studies in Part B

I am very pleased with this Course,

I learned a lot, Dan is a great teacher. I was a bit worried about the pre-requisites because I only had some knowledge of C and assembly but could manage to do it with a lot of practice :) I really recommend it.

I really think it a wonderful course that I've never experienced before, thanks to the instructor, Professor Dan, I've learnt a lot about PL and FP, which seems opening another new window towards another new programming world.Strongly recommended!

Fantastic course - it's real computer science. Request to Professor Grosman: Would you please combine the 3 course sections in to one packaged certificate? I like that the course is broken up but the 3 certificate URL's is logistically difficult

Great course to push yourself from Advanced-Beginner programmer to intermediate one. I have taken many courses in this domain. This course is one of the top-notch courses. The only quality course, in my experience, that matches the level of CS50.

A challenging but awesome course that teaches a lot about functional programming. Really needs 6-8 hours per week though. Has great PDF lecture notes, homework structure and you can easily use the learned concepts in other programming languages.

Very nice introduction to FP and Dan definitely has his heart in the course. The weak points are Emacs (but can use other editors or use online sandboxes) and peer reviews (I got a review with 3 points for every task and comments like "cxatiu")

Very thorough course on programming languages and their concepts. Despite being a self-taught software engineer (more like a beginner-intermediate programmer) for 5 years, I found some of the material new and advanced, which surprised me a lot!

An interesting introduction to functional programming. This course can be a little more challenging compared to other MOOC's if you do not have prior programming experience. You will learn a lot about the concepts behind programming constructs.

Really really good course. The pacing and the rate at which the difficulty goes up felt really really good. I don't know if I'll ever use functional programming but I'm happy to have learned a little about it either way. Will do part B and C.

The best introduction to functional programming I've seen. The course lectures make for a smooth learning experience and the exercises in the assignments range from simple to moderately challenging and are a good complement for the lectures.

This course (including parts B and C) was truly a journey, and a delightful one!

Thank you so much for putting this together, and transmitting this wealth of knowledge with so much enthusiasm. This was truly engating engaging as result.
