The answers given by us are not accepted by you guys. I don't know why on earth do you people design such courses whose questions are itself wrong. You guys are making us perplexed and puzzled at the same time. We are investing time for learning something and instead you guys are taking money from us and creating a big fool of us. If you have proper formula towards certain problems why don't you prescribe in your videos? Why are you harassing us? Is it because you want us to spend more number of weeks against the 2-3 problems of these above mentioned weeks and you will get more money from us? The policy won't work if you can't rectify your mistakes and moreover this course is strictly NOT TO BE RECOMMENDED TO ANYONE... Its that you guys have a certain set of answers to those problems and those answers I CHALLENGE YOU THEY ARE FILTHY WRONG. I HAVE SPENT TWO DAYS WITH THESE PROBLEMS. I HAVE 24 HOURS IN HAND LIKE YOU HAVE. PLEASE DO SOMETHING CONSTRUCTIVE AND DON'T PLAY THESE VISCOUS TACTIS WITH US. I see there are so many students who are asking for help and you guys can't even answer to the problems. Shitty course.. shittiest of all I did....My bad luck in trusting people like you and losing money in return. Shame on you. If you can't handle with the subjects at least don't make us confused and don't make a mockery of yourself. Worst service ever.

Explanation and teachers are perfect. But some questions in quizzes are wrong and moderators don't answer in discussion forums

really amazing instructors...thanks a lot for taking the efforts to teach us these simple yet elegant topics

Very informative, instructors are very precise.

The course is tough but worth the time.

very interesting course.

This is a great course

Quiz is too difficult and there are no hints
