A​ lot of effort was put into this course. There are some great lectures, but most of all you can learn a lot from the assignments. These assignments are quite challenging though, so expect to get the most out of this course only if you put a lot of work into it.

WHAT A WONDERFUL COURSE,I HAVE LEARNT SO MANY THINGS.I RATED FIVE STARS BECAUSE THE LECTUERS ARE EXPLAINING VERY GOOD AND THE QUIZS ARE VERY AWESOME,ESCPECIALLY ASSIGNMENTS MAKE US TO THINK OUT OF THE MIND.....

THANK YOU TO COURSERA FOR GIVING THIS WONDERFL COURSE

Interesting and hard (but possible to solve) challenges. All necessary information to solve a problem can be found in the lectures. The theoretical part is minimal but enough to start solve advanced problems. That's why I love this course more than others ever!

It is a must course for anyone who wants to excel in computer science field, and this course will help in every possible way from easy explanation of topics to effective assessment along with helpful discussions.

Thanks for creating such a wonderful course.

Lots to learn and it's fun to learn from different teachers. Very heavy (and high quality) course if one wants to do proper justice to all the materials presented (especially hashing and trees... Week 3 onwards). A worthy investment . Enjoyed it immensely.

Nice course, It was bit difficult for me. I think I will have to go over the few lectures again soon. Problems were very cool, these took lots of hour head down. Thanks all lecturers, specially Daniel M Kane and Alexander S. Kulikov. Loved your lectures.

Similar to the first course in this Specialization, a great course on algorithms and their applications. Frustrating at times, but I definitely recommend this course (and the others) if you are serious about implementing algorithms for whatever purpose.

I appreciate the fact that our lecturer put a lot of efforts in Practice case study and Coding practice along with most of the theories covered. This is one of the best course I've learned, which help me to understand and "digest" things in easy ways.

This is a great course to learn Data Structures. All the course materials are very helpful and easy to learn. The instructors are very focused with the content; they explained every topic very clearly and easily. I have learnt a lot from this course.

Great course, hard and challenging.

Couple comments.

Please use pen during lectures easier to follow and understand .

Some assignments require more then 8 hours to complete so please add to description of the course

(don't make assignment easier)

State-of-the-art programming techniques with detailed explanation of methodologies and why they are more efficient than basic solutions. Difficulty of the programming assignments ranges from easy practice exercises to really challenging problems.

It is a great course. But it would save a lot of time, if we could actually see errors of our submissions. Checking if your algorithm is working correctly (output wise), when you actually have a stack overflow on some test is very frustrating.

This course helped me clear a lot of doubts as well as it introduced me to many useful things with their implementation. I must say this course is one of the best courses available on Coursera. Thanks to great instructors who helped me a lot.

Clear presentation of basic data structures with non-trivial applications. Material is presented very well for beginning coding or as a review. Online grading is better than many programming courses. Works well as a stand alone course.

It was a wonderful experience in learning through this course, Thank you Coursera and University of California San Diego along with the National Research University Higher School Of Economics for making this course available to us.

pros: Very nice course, understandable materials, great instructors. I am very likely to recommand this course to my friends.

cons: The BST and AVL tree part seem to be a liittle unclear. The pseudocodes are not fully implemented.

This is a great course. The lectures were easy to follow, CLRS references are also good to clarify anything that is not covered in the videos. Programming assignments are challenging enough and spot-on to practice the concepts.

All explanation are on the point no more irrelevant content, the way of teaching is so good as a person who has less experience in programming can do it and learn the most important and interesting topic in Computer science.

At first, I think the homework is really difficult. Since it seems like there's black box test.

But gradually I get accustomed to it.

I've learned a lot. And I can felt my growth clearly after conquering some difficulties.

It was really not easy to pass this course. Some problems took several days for solving, but this is the way a human being studies. If the course is easy, then everybody can pass it and such an easy course has no value.

Once again, I am very pleased with the course in this specialization. Continues with the rigor and learning approach from the previous course, Algorithmic Toolbox, and builds upon it. Looking forward to the next course.

This course is so useful and has helped me to understand what's really going on under the hood with the Java Collections framework. I have no doubt that I will be writing more performant code day-to-day thanks to this.

This course is really good. The way it is planned and taught is really appreciable. It contains really good problem. This course is for them who really want to improve their programming skills and their code quality.

It was a very helpful course.It was easy and at the same time very challenging.All the proffesors are great.I highly reaccomend it to everyone , do give it a try , specially if you want to keep your brain working

A highly-recommended & very useful course as part of building computer science base knowledge. Got introduced & practiced multiple data structures which was a must for me as I am not a computer science graduate.
