great!!!!!!

After so many years, I actually understood the core concepts of data structures. Thanks all three instructors. The amount of effort they are putting to make the things easy for the students is awesome.

Fantastic, enjoying and challenging.

Clear & Explicit!

Amazing course with amazing teachers .Worth every penny .

This specialization is really efficient. I passed first course. And I'm now on a way to complete this second course and go forward.

Very good course. This is a very right course for Java learners, will be touched on all basic stuff that are needed in Java. I will highly recommend this course for my colleagues.

Very good course ! The topics covered in this course are very useful to start code more complex functionalities in java.

It was really a very good course, you can learn many data structures and its implementations along with programing assignments and quizes which are quite challenging. The idea of concept challenge was awesome. You could learn performing efficiency of the algorithms, benchmarking, linked lists trees hashmaps and other data structures.

detailed and condense lecture, lots of hands on practical project

Interesting and practical course.

Excellent specialization

Very good course for Java programmer for Dara structure and performance.

As all your coursers, great! I have learnt a lot!

Content is well organised and explanation is really very good

Interesting project assignment

The data structures are basic in this course. But I loved working on the project. I had first hand experience on how to use Java to code these structures and I think this will help me a lot in the future. The course is well designed and I would recommend it to anybody who wants to learn Basic Data Structures with Java well.

Great into to Java, instructors have clearly put thought in to the format with the choose your own learning style videos, and additional coverage where it may be needed. These have been very helpful.

Very solid review of data structures. In fact, I learned a lot of new things along the way like how to benchmark test Java code and how to properly use JUnit and other unit testing frameworks.

Never know anything about Data Structure before this course and it changes everything!!! a MUST for any CS student or professional.

Excellent Course. This includes useful Data Structures. The Programming assignments are helpful. The instructors have done well to explain the concepts clearly.

Great course to refresh my memory on data structure that I haven't been thought about after graduating from college.

The course curriculum is well designed and teaches students the basic data structures needed to be a successful software engineer. The project is good, and the weekly assignments are challenging.

Challenging. I learned a lot.

Great course!
