I got a spelling mistake of my surname on the certificate.please help me to fix it

Very Simple. Not explaining Enough Concepts. I did not understand concept quitely.

If you don't already know all of the class content don't expect to learn anything

The functions and some other parts are very cumbersome and not explained well.

I cannot download my certificate, kindly help me to download my certificate.

Absolutely disappointing course, minimal engagement level and taught nothing.

Videos going too fast and not very good quality. Also, labs have many errors.

Detail explanation required and there is no basics .Please start from basics

Very poorly designed and inconsistent course!!!! Wasted time and money!!!

this was the main interest in my certificate and it was way too basic

Not practical enough. Overall system of education was not chosen best

I feel it was just too fast and should've included an assignment.

Not being able to get your certificate without paying is crazy

Not very easy to understand.Concepts are not well explained.

Theory good, but examples are bad since Labs are not working!

robotic voice. not enough explanations, not enough exercises.

Aburrido y poco practico. No son claros con ningún concepto

It should be in regional language for better understanding.

Cannot proceed the course smoothly because of tech issues.

Seriously, please stop begging us for using your products.

horrible esta en ingles...hay mejores curso y en español

Please update the content

Slides are still from 2016/2017

no certificate given after the completion of the course

Poorly done. Needs to be edited for content and errors.
