Los ejercicios son muy dificiles y hay que hacer mucho reaserch en los foros para lograr llegar al resultado. Las pruebas son diagramadas de tal forma que a veces es dificil llegar por errores pavos al minimo resultado esperable para aprobar los assignments (ej run_ttest)

Content was well paced and well presented but the auto grading submissions took a long time to get used to and were very stressful. The recommended time to complete the assessments was also very optimistic, most assessments took me easily double the time suggested.

A bit surprised by the low volume of teaching material, and the energy required for completing each assignment.

But a posteriori, it forced me to really engage in the learning. I will probably remember more this way, than if I had listened to dozens of video...

I found some assignment questions quite unclear. This, together with the grader sometimes marking answers as correct even though they were wrong, forced me to spend many hours trying to find the underlying problem to incorrectly answered questions down the line.

The professor is going too fast and the concept isn't getting cleared. I wish he used some digital board to write atleast what is trying to say or write how the different functions in pandas,series,numpy works.

Although, the assignments were of high quality.

Although the course helped me learn about Data Science. the session taken and the assignment were different and had to understand the expectation in the output.

But overall it helped me understand how can we proceed with studying Data Science through Python

Lectures were OK. The pace moved really fast, and I thought the hardest part was that the directions for some of the questions weren't really clear (and I spent sometime trying to figure it out but gave up --- still passed though!!). Thanks for the course.

For the beginners, It's little bit hard to cope up with the submission according to the lectures. Lectures seems easy but when I go for submission, it seems much difficult and requires more study than the lectures which are not mentioned in the lectures.

this course is definitely not for beginners, I as a beginner had a hard time completing the assignments as I had to read most of the functions used from pandas documentation and it took me a lot of time. please introduce a more beginner-friendly course.

From my poitn of view more lessons are needed, achieving exercises require a deep search on stackoverflow and other courses. That shouldn´t be the goal of the course, I expected the lessons to give enough knowledge to fullfil the questions of the exams

The tasks were longer than stated. The emphasis should be more on the skills than on heavy tables. I found the data too complicated. Especially the last assignment makes it very difficult to accomplish the course.

There should be more smaller tasks.

Too much information to absorb within 4 weeks course, requires to spend lots of time offline in learning and researching the Python codes to resolve problems in the Assignments. WOud recommend for hte proficient programmers but not for the beginners .

The teaching process is too fast, especially the assistant teacher who appear at the end.

The assignment is 40% related to the course. And a little bit hard.

The first week assignment is related to the week two, but i did not study week two at that time

The explanation provided and the expertise needed to complete the assignments were way apart. People with great grip on python and having basic knowledge of pandas library will find this relatively easy. The assignments are challenging and hence good.

The selection of topics is pretty good. Besides that, the videos are more boring and less friendly than similar free material available in Youtube. Also, some of the graded assignments have bugs, so you will spend some time trying to get around them.

The instructor is nice and course content is very good. But with respect to what he explains, the coding is way too fast to catch up! Also, not all for beginners. One should have intermediate knowledge in python and at least beginner level in Pandas.

Good course but the assignment grader can be annoying as it is very sensitive to data types and data formatting. I get that this is one one of the constraints of auto graders but on a course that is centered around data it can become very frustrating

The course was easy to understand. The reason i'm giving 3 stars is more on the preparation of the entire set of courses. They kinda develop as the course goes. The other 4 courses of the specialization were not even ready after this course was done.

I spent over 150 pounds on this course which is suppose to be less than 40 and last for a month. I work and studied this course at the same time, I would advice to check your price policy because it is definitively not for those in full employment.

I found the assignments strangely difficult, and their difficulty wasn't sourced in the right place . For example, when solving assignments I never went back to see the lectures, but spent most of the time googling syntax, method signatures, etc.

I felt that the lectures could have been more helpful. There was a lot of talking without actually writing down and explaining the concepts. Even when there were demonstrations, he breezed through them without explaining what each part meant.

Looking for some more references for practicing lambda and list comprehension.Assignment auto grader is a pain, it does not give clarity on the answers submitted. Having some detailed explanation on the assignment and approach used will help.

The lectures dont include almost anything from the programming assignments, I had to look for everything on stack overflow. The explanations are great and I learned a lot on the assignments, they are just 2 different things most of the time.

The material is good, but the assignments are incredibly messy (perhaps that's what you're supposed to learn!): errors are never fixed, it's still using pandas 0.19 (this isn't even mentioned) and you can see the course is simply neglected.

Interesting perspectives on data from knowledgeable professionals, but lacked some hands on learning that I was expecting. Timelines to complete technical assignments were ridiculously shorter than the actual time it took to complete them.
