With all due respect but this was honestly the worst paid education-experience I've EVER had in my whole life! What is this?

Okay let's summarize the problems:

First of all. This course does NOT provide any useful math skills. No, in the first 3 courses, you learn a tiny piece of minimum basics of college math.

And then comes week 4....... what.. is... this... why.. Any note written on the screen looks like the drafts of college times, where we had no pleasure to even write.

It's totally hard to even understand what is being "explained" nor to even READ what is being written! It's a total loss of time and money. The only thing worth in this course is the title of the course, written on the certificate. But there absolutely NO quality behind it! I'm honestly disappointed.

Half of the quiz-questions are very misleading because of lacking a proper, clear and distinctive use of language (is this math or not???)!! The theory PDFs are okay at the beginning then get worse with each week. There is such a lack of clarity proper explanation!

please just delete this course.

PS: it seems, the discussion forum is not even touched by providers. Why? There are a ton of suggestions to improve the course. I mean... there WERE... if someone would read them to actually improve the course.

PPS: And HOW did this course get 4.5 Stars?? Makes no sense to me.

This course was pure garbage. Though it seemed promising in the beginning, it was clearly too ambitious and poorly designed. The topics are too quickly covered, and don't build upon each other. It's a very disconnected learning experience. The probability modules are completely useless. The "instructor" just read some definitions and sloppily wrote some formulas on a virtual whiteboard. Though I appreciate the exposure to a wide array of topics, my time would have been better spent reading a book on the same concepts - an exercise I will inevitably now have to do.

T​he course is divided into 4 weeks. Topics in Week 1 and 2 are explained very well. But Week 3 and Week 4 are just useless. There is no teaching in Week 3 and Week 4, just writing down the formulas present in texbooks.

T​he reason anyone wants to take courses like this, online is to understand how the formulas shown in text books work and have a deeper understanding of the topic.

B​ut unfortunately the topics in Week 3 and Week 4 were just presented as it would appear in a text book, no teaching there.

I chose this course because it said it was for beginners but the content was extremely difficult and was not at a beginner level at all. The presenter assumed knowledge and the presenter himself made errors during his presentation and did not explain concepts well. The quiz was very difficult to attempt because the questions often went beyond what was in the course. Do not attempt this course if you do not have actuarial science level.

I expected much much much more than what I was exposed to in this course. The video companions could be more detailed, having more examples (I believe math is learnt via examples) and the lectures, especially in the third and fourth weeks were amazingly disengaging.

Please give the certificate sir.

Why didn't i get certificate? I have tried a lot to get this one, i have lost sleep for many nights. Im coming from a poor family. I dont have enough money with me. If i get this certificate it will help for my career.

Help me sir..

I think this is not the best course to start with for the data science learning path. The first half was maybe too easy and the second half was hard and confusing. It's discouraging for a person who is just starting with data science.

The course was not properly taught. There should have been more quizzes, more systemic approach to explaining the problems and solutions. Also the feedback after exams and quizzes were non existent

The course provides very basics concepts of Mathematics and Statistics.This course would help those who needs fundamental acquaintance with basic theorems of Mathematics and Statistics.

j guess I would be better suited to a course for pre-beginner beginner levels. This has been over my head since the first video.

First, its too easy, almost intuitional. Then it overwhelms you with a plethora of formulas, no mathematical logic provided.

very poor instructional videos. videos and examples in videos are extremely hard to follow and not well-organized.

Found too many errors in both content and quizzes. Good basic course for beginners. But, the errors must be fixed

Numerous errors in the videos, very bad audio quality. Not worth the time.

Extremely Basic. Not useful for DataScience in my oppinion.

I UNDERSTOOD MY DOUET IN THIS COURSE CLEAR IN DATA SCINCE

I don't recieve the certificate the course is good

I want to unenroll from this course

Too many typos in the videos

Terrible, just terrible!

too basic

too easy

Boring
