The math in this course is quite difficult, but the professor does a great job of explaining it in a very easily understood way.

very challenging fast-paced course

I was very amazed with his really good lectures. Especially proving each algorithms correctness and performance was very interesting and stimulated my curiosity. I also need to note that optional videos for probability helped me a lot to understand this course. I would like to recommend my friends definitely.

Great course to improve your skills on Algorithms, Space and Time complexities

Professor Roughgarden makes algorithms cool. With his passion for the topic you cant help but get excited about it too. I feel like I got a deep understanding of the topics covered versus just learning a recipe to sort an array. Looking forward to more.

Needs hands-on experience with high-school probability to help crack the exams

Best online course and one of the best courses in programming

It would be nice to see more examples especially were we have too many formulas. I still confused with probability.Also hadwritting isnt really helping. I am most of the time decoding scripts. In addition he is reading the formula at one moment and in around 3-4 seconds it appears on the screen. So I kind of listening him while trying to read what is happening on the screen. horrible experience.

Personally, I would recommend this course to anyone who really wants to learn how things work in that sort of algorithms. I found the assignments a little difficult, but also extremely helpful.

It´s been a long time since I had so much fun. Like going back to school. The course was great, the material is excelent, the assignements interesting and challenging. I really liked this course and am getting ready for the next one on the series.

it was awsome!! one of the best courses and materials regarding algorithms i have taken!thanks a lot!totally worth my time and money =)

Great course with interesting assignments.

the tutorials is not for average students, it takes a very high skill to understand them . also the quiz nd the assignments r too tough.hope you can make them a bit easy, the last one ,ie with graphs and trees was a bouncer. If the maths required is so high, please take a week to first explain the math fresher required in course and then start the main course

This is great course

Its an amazing courses aiming to high-level and fast-pace algorithmic thinker.

I enjoyed this course, it was more challenging than the first one in the sequence, especially in the graph-search portion. The last 2 weeks are much more simple, but it is still essential for any serious student of CS to learn about data structures, especially common and practical DS such as heaps and hash tables.

The professor is amazing. He has the ability to present the material very clearly, concise, and with a good dose of humour! I would definitely recommend it to anyone interested in algorithms and data structures as an undergraduate or a professional.

good in depth knowedge.

This was another good one, providing a slightly deeper dive than I had seen in other courses. The big revelation here, for me, was the addition of Bellman-Ford algorithm for evaluating shortest path in networks (graphs) that have some negative distance values between nodes.I also like the approach to data structures (high-level, then drilling down into increasing detail for level of interest) I find it hard to say I understand a data structure based on Interface and Theory and I would have felt the certification meant more with at least a rudimentary implementation. I guess that makes me a coder at at heart.I am about to jump into the next course of the specialization: Greedy Algorithms, Minimum Spanning Trees, and Dynamic Programming As with the two courses before, I am expecting new revelations about the kind of programming issues Ive been solving for more than fifteen years.

A really good course

Useful refresher!

I learned a lot lot lot, no more to say. Fantastic.

very good course! but I think this specialization focus on mathematical analysis, we need to practice more

Great course, at least for people like me who lack of computer science background.

This course let me feel algorithms is not hard as I thought. It is worth to learn

I really enjoyed it. Perfect balance of practice and theory together with clear explanations. I also appreciate the mentors efforts that always answer any questions and try to help. Thank you Tim, Vassilis, and Arjit.

This is a great course. The teacher is very clear, and the material is very interesting. The programming assignments are interesting: the problems asked are very simple, but the input is generally too large to use brute force: you really have to implement the algorithms presented in the videos. This makes you realize how much smart algorithms can make a difference.The level of the class is relatively high, compared to other Coursera courses Ive taken. If you want some serious training on algorithms, look no further.

Good learning

Nice course and exams problems. I recommend this course if you want to understand the basics of graphs, trees and heaps.

The material was a little light and far fewer video quiz questions to test our understanding of the material. I also tried to test myself on BFS and DFS by doing online quizzes like geeksforgeeks - bombed really hard.

Excellent mix of math (not too much), programming details (probably needs a little bit more) and practical applications!

This is great course and amazing refresher!!!

The early part of the course does not make a compelling argument for why we need to analyse complexity. The lectures are interesting but not helpful for use in business.

Super interesting course, I have never seen in my lifetime.Watch me ;))

I am really satisfied by the course .....just love the lecture and slides too :) .....

Tim does an excellent job explaining things at depth and at the same time keeping things interesting. The quizes and programming assignments are well thought and carefully balanced vs the material taught. They force you to stretch just a bit beyond the lectures, which is a good thing IMHO.And there is a wealth of advanced/optional material for the curious.

I love how clear the videos (and notes) are and re-watching them really helped a lot! I wish there was more discussion on the forms though!

Its challenging but interesting.

The best Coursera class I took so far! The instructor has a good pedagogic approach -- for every problem he discusses, he starts with an intuitive explanation illustrated on a simple example, and afterwards provides a rather rigorous justification for the algorithms (omitting only secondary details).I found the problems challenging, and the quizzes required quite some thought, not only repeating/slightly modifying statements made already in the lectures. This made it feel closer to a real class than the other Coursera courses I took so far.

Very much to the point, no nonsense, good course!

Many of the weeks videos were out of order.

Week 4 was significantly more time-consuming than the others, but it is still an excellent course overall. Recommended!

Well done!!!! That is the first English course I have finished!!!!

Well done, made a very difficult topic accessible.

if u do those math it will definitely help u to be advance

Its a very nice course if youre doing some refreshing of college chemistry.

The material was good, but I did notice a couple of lectures and in-course questions presented out of order. What really turned me off, however were quizzes. In weekly quizzes the first answer was always the right answer. In the final quiz most of the questions had the first answer as the right answer. Since randomizing the answers is so obvious and easy, I am really at a loss why the quizzes would be presented in this way.

A lot of calculation errors and incorrect answers

Great!

Excellent course, very challenging, instructors take the time to explain the work very well.My only suggestion would be that week four be split into two more manageable sections, as it was quite large and there were many different topics covered. As aqueous equilibria are not my strong suit, it was a lot to take in

Thank a lot

Great Course

The course is well-structured, clear and coherent. The assessments are quite good too. Recommend it!

Excellent course. If you are struggling with high school chem, or need a good foundation for college chem - this course moves you through the concepts and gives you lots of practice problems.

It is a good course for beginners, but it is too slow for advanced learners who want to refresh their knowledge.

I did the course before. It was amazing!

I am new to teaching AP Chem and this class was a great refresher for me....I suggested that my students enroll.

Although I had taken this course and higher levels in the past, there are still many subjects that I do not feel I have mastered them. This course helps me to achieve that goal. Also, it does not mean that this is not a flawless program, but by far is much much much better than the program I had attended in the past.I like to appreciate both instructors for their time and the effort they have put into making these wonderful videos for many students around the world!

This whole program is so knowledge-giving...thanks to Coursera and University of Kentucky.😊

There were some mistakes and weird glitches, but overall solid overview of second-half chem

Great.. Im chemistry.. And this course is very useful to remember all things have you learnt in the university... Thank u

This is realy helpfull and interesting.

Itts great! Nicely explained with step by step resolution of problems. I loked it :D

Great explanation. I am very satisfied.

thank you for the course. great

i like it but there is ALOT to do i am 13 taking this for science class and i am starting to get lost in what the are saying

Needs some means of feedback. Several times I felt sure that a question was wrong, but theres nothing to be done about it. Additionally, it would be nice if, after completing (and passing) a test, you could see what you did wrong and how the answer should have been determined.

very easy to follow

The course is very well organised and presented.

Very Good course ! Hope to see Organic Chemistry and some Biology courses by University of Kentucky like this.

Its great! Thank you for everything :))

amazing course. all topics about chemistry are here, very good quizes. a good course

I used this course as a significant portion of my preparation for the CLEP Chemistry exam, and passed today with an A! Thank you!

This was a fantastic course! The teachers taught the material well and were entertaining in their teaching methods. I enjoyed that the lectures were easy to watch, and I appreciated all of the practice problems.

kind of boring and I am not learning how half this info is obtained or why it is relevant to real world chemistry

Thank you for reviving my interest in chemistry!

The subjects are very well covered. Great explanation. Very recommendable

Excellent lecture videos with practice problems that are very helpful in recalling the chemical concepts. Really wish this course could offer at least an SOA so learners can be more motivated.

Thoroughly enjoyed this course! Problems and assignments are quite challenging but doable

Very challenging, well presented.

This challenging course improves understanding of algorithms and is intellectually stimulating. I learnt the theory behind algorithms and how they are applied to solve real world problems.

Awesome! The professor is obviously very knowledgeable about the ancient Greece history and its a pity that Im done with the course; I wish I could attend the full, comprehensive version of it! On top of the basic history, I appreciated the comments on the research method, the nuances in the interpretation of different events, the presentation of additional elements (e.g., pictures, maps, artifacts) to support the lectures, etc. I was sometimes rushing a bit to go through all the reading assignments but Im glad to know now what to read and where to search to get more information on the topic. I think its one of the good side-effect of this course: it motivates you to learn even more about the ancient Greeks. Thanks!

Very good. The readings indicated helped to expand my knowledge of Ancient Greece. Every undergraduate student in History, Philosophy, Archeology etc, must take this course.

Great course! Very touching and devoted instructor.

Excellent overview and introduction to Greek history. I am travelling to Greece later this year and wanted to get a better understanding of Greek history to appreciate the art, literature, architecture and sites which I will be visiting. This course was both educational and entertaining. I highly recommend and look forward to building upon the knowledge acquired in the course. Thank you!

The course was fascinating. At first, I must admit Professor Andy seemed quite dry at first, but as I began to understand his wit, I waited continually for him to deliver something extremely hilarious. I still laugh when I think about the reference to Bats whispering. His understanding of the topic was excellent and his ability to communicate such a tremendous span of critical Western history efficiently and in an organized manner made the course valuable to me. I learned enough to of course understand I knew little, though I have written down several areas I want to research on my own to expand my knowledge. Great course, great lectures, thank you for presenting it to us and helping us learn!

Ancient History: it is not boring anymore (for me)! Charming Prof. Andrew Szegedy-Maszak gives materials in a way, that you feel an every character (even mithological) was a real person involved in a real story. I also like nice sence of humor and a voice of lecturer! A lot of reading was easy and interesting to learn during the course.

A fantastic course: Very well-presented and hugely informative.

Great course !

Comprehensive course. I gained a great deal of information that helped to fill gaps in my own knowledge base.

Great Job. Andy definitely is the best.

Excellent course. Really inspired me to learn more.

What a great course! I have enjoyed it a lot!

Very Interesting course that covers a huge range of topics over a long period of time. A very well informed lecturer who can speak about the subject matter in a clear and concise manner.

Fantastic Course! Really well structured, lectures are really interesting and I have really enjoyed it!!

Well prepared course.

Some great material and I learned a lot. I did in fact complete the course but chose not to submit written material. Sometimes the lecturer was perhaps a little dry.

Great course! Loved everything I learned.

Excellent course. It has a perfect rhythm and the teacher has a good pronunciation which it is a important detail for no native english like me. I recommend strongly.

Fantastic course. Information packed, but not overwhelming. The links to online readings provide nice context for a lot of the lectures, but werent in any way daunting. Highly recommend!
