Very amazing course. Great teacher Great explanation. From zero, I know a very lot about data science and its process from this course. The way he taught, his slide and his explanation are very easy to understand. All of these make me want to jump into the data scientist world and take other Kirill's courses right now. Again, very very amazing course, I highly recommend this. Very statisfied.

A very valuable and comprehensive initial course in data science. The sections on data extraction, load, and transformation were especially valuable. Kirill also provides numerous real-life examples from his years of experience.

Very good and comprehensive data science course, not the most modern technology but absolutely very beneficial to someone who wants to develop understanding of data science! Highly recommended

Great introductory course on practical Data Science concepts and procedures. Avoids the pitfall of getting sucked too deeply into statistical math. Kiril's presentation is first rate. I especially liked his use of many small video lessons, which makes the course easy to consume and also makes it easy to use the course material as a reference later. He comes across as very approachable, dealing with typos and short-term memory lapses just like the rest of us. The only flaw, if you can call it that, is that occasionally he re-explains a point too many times or gives more hypothetical examples than necessary, which can drag out the lesson. But overall I'd rather have an instructor err on that side than that opposite. This course has given me the confidence to dig deeper into Data Science. I'm heading on to more courses, but most importantly I feel ready to start practicing on real projects.

Kirill is awesome. He is enthusiastic and explains so well! However, in this course too many topics are taught. I would suggest you to take specific courses like A-Z Tableau, or A-Z SQL. Also there are just few homework practice examples at the end of the sections which I need the most!

Overall, it is a great course to warm-up in the world of data science. The course is very well structured - ETL, model, visualization and presentation. The instruction have great practical knowledge on the material. Maybe I had higher expectation of the course since it is named "A-Z", although I felt that "Applied data science" or "Practical data science foundations" would be a better suited title. In summary, good introductory course into data science. P.S I am taking A-Z Machine learning next from Krill, so hopefully it will cover the gaps!

The English pronunciation could be better. Confuse me sometimes. Btw, I am not come from English-speaking country

Kirill is one of the best teacher on Udemy ! Really useful course for a beginner in Data Science. I chose the Data Scientist Path and therefore I will continue with the R programming course. Thank you Kirill !

By Johnny Torch on 3 weeks ago

Amazing learning journey in a dense and wide subject. A great deep dive in the real life of a data scientist. Real effort to explain complex things and make them simple but not too simple. Very informative and full of visuals and step by step explanations. Kirill is doing once again a great job. It really helped me clarify what data science is all about and in which direction I want to go further. I enjoyed this course very much.

By Bansari Kothari on 2 months ago

The course was wonderful and it gave an overview covering all the parts that are mandatory as a skill set for a Data Scientist, I'm glad to have enrolled myself for this course. Thank you Kirill for the amazing explanation!!
