Avis et commentaires pour d'étudiants pour Les outils du scientifique des données par Université Johns-Hopkins

Complete waste of time. This should be a course on its own, and much less be charged for. This should have been the 1st week of an actual class. This only dealt with installing a couple of software tools. Hopefully the following courses will teach something worthwhile.

Very bad course so far. Very little detail and Assignments are very hard to solve. Worst $500 dollars spent in my life, and the course isn't worth even $10!

I'm an online instructor myself and the quality of the course isn't worth its price!

A simple list of programs that needed to be installed would cover 90% of the course content. Some of this content is also repeated in other courses in the sequence. If you have any technical skills this entire course is extremely tedious.

Although the content is correct, quality models videos and materials is very low, wanted to make all the specialization, but I'm not satisfied with the quality of the course. It's a shame, because the JHU is an excellent University

If you are doing this for certification then go ahead, but if your intention is to learn then this is not a good course. Its absolutely basic and most stuff you can find online without spending any money. Wouldn't recommend.

In my opinion, most of this information should be free and available as a pre-req. for other classes (installing R Studio).

It was cheap, but in general, I thought I was going to be more out of this course than I did.

Students generally move towards online course to hear a human explaining them those concepts. This new technique may be time saving for you but it was really annoying and unexpected (almost everything )

$40 is way too much to spend just to learn how to install a couple pieces of software and sign up for a GitHub account. The entire course should have been the first week of the following course.

Is this a real course for a data scientist just installing shit and a peer reviewing for that screenshot and forking all repos ...very bad not worth to be with rest course in specialization

Good time of day! This course is great! But I can't finish it as I missed deadlines and can't switch session!!! I missed 1 month already because of this bug:(

It's so frustrating...

Me inscribí en el curso y solicité una ayuda económica porqué supuestamente se dictaba en castellano. Pero esto no es cierto y no puedo avanzar. Por eso mi calificación en baja.

Too basic content.

I have not learned anything with this course (installing R and RStudio should not be part of exercises or lectures).

I hope R programming course will be better

This is pure theoretical course,

It's look like a Power Point presentation. Students can not easily understand this.

I do not recommend this type of teaching on Coursera

Some interesting concepts, but way to simplistic in my opinion. Only reason I see to pay for it is the fact that it is a requirement in the Data Science Specialization

Do not take this course if you want to get a job in industry. Python now dominates industry and R is basically obsolete. I will be switching to a course in Python.

Certainly not worth paying for this course, only talks about how to install the tools.

Not able to take quizzes when you try to take the course for free.

Good introductory course. However, an overkill as a separate course (and hence charging $30 for it). Courses 1 and 2 could have been clubbed together.

It has almost no content and isn't actually useful. I've heard later classes in the series are way tougher, so the ramp up isn't at all good.

Not really enough content to be a course in it's own right, should be additional material as is useful, but definitely not a requirement.

It is really basic course, I expected much more even if this is offered only for $29.. (the cheapest course in the specialisation)

I think a few people like to hear the mechanical voice. Some videos have really low resolution and it is hard to see the codes.

Eu achei o site desorganizado, não sei se concluí ou não o curso. Não sei se executei todas as tarefas ou não. Decepcionante

Completely useless. Just a number of boring videos of what you may possibly learn in Data Science Specialization.

Not worth the price. Extremely basic stuff spread very thin over too much time just to be able to charge for it.

Useless. The information content is close to zero. Just some blah-blah and a long tutorial to install software.
