Data36 Reviews 

Tomi Mester takes the time to explain really well the material he teaches.
He is proactive and responsive and kind.
Most importantly, he actually says the truth about Data Science being a difficult field for which one must be ready to invest time and interest. Data science does not get learned over a few months through an odd online crash course.

Great stuff!

This course is incredibly complicated to set up and I ran into tons of errors, when I asked for a refund with his 30 day money back guarantee he ignored me and did not offer a refund. I find this an awful thing to do and immoral.

I have just completed the Junior Data Scientist Academy 3 months online course. I am really happy I chose this course over the many other data science courses.
The instructor, Tomi Mester introduced me the word of data science. Command line skills, Python coding, SQL, statistics, machine learning and business thinking, the full set of knowledge what is needed to start a new carrier or a hobby project in this interesting field.
Tomi started the video tutorials by explaining very basic commands and queries which anyone without IT skills could easily follow. Then he guided into more and more difficult tasks and topics, and a little bit later I just realised that I am writing a quite complex code. His enthusiasm is super motivating. When he posted a new task, I couldn't wait until the end of the working day to get to it. Tomi’s presentation style is exceptional, he explains even the most difficult topics in a very clear, logical and easy-to-follow way. Tomi and Tamas were always available and supported me during the whole course, they gave me meaningful and informative response within a short time.
The structure of the course is well established, the perfect rate of theory and practice. The tasks were carefully designed to practice the content of the video tutorials and made me think a little bit further on my own.
I have already registered for the Data36 new Data Source course, to further develop my knowledge on data scraping.

The quality of content that Tomi is putting out is just great. It helped me a lot in clearing technical interviews of some really amazing firms

The data36.com junior data scientist course is a very practical, very intensive 6 weeks long learning experience. I have learned a lot, and had the opportunity to watch deep into the rabbit hole. I recommend this course for everyone who wants to improve itself in data analytics, data-related coding, automation, and also a little bit of machine learning. After the 6 weeks, I have already started to use what I have learned in my very first data science pet project.

A really educational course!

I attended the Junior Data Scientist Academy. I was fully satisfied with the course, materials are easy to understand with full of useful examples, and it's all very practice-oriented.
Also great support system, you are definately being taken good care of during the course which is encouraging!
Would highly recommend for those who wish for a more interactive learning experience.

I have completed all three courses available on the Data36 website - the 7 day SQL course, the 6-week junior data scientist (JDS) course and the A/B testing course. All three are amazing and teach you so much more than any other coding course I have ever taken (I’ve taken a few!).

Why are they so good? Because you do all the work yourself and that’s the best way to learn. Everything happens on your laptop - there is no external platform where half the code is pre-written for you. And the code you are writing is similar to the type of code you would write in a real business environment. If you get stuck, you can email the course creator, Tomi Mester, for help and he is always so helpful. All the courses are video-based and very informative and there are also many useful blog articles to read - I frequently go back to the website when I need a reminder on how to load data to SQL!

The JDS course in particular is excellent - I learnt so much by completing this course and also managed to create a few projects for my GitHub portfolio because of it. I was then able to add these projects to my CV and was offered a job in a data analyst role just last week (I took the course in July 2020 so it took less than a year to change my career direction)!

I would recommend all the courses on Data36 to anyone who wants to pursue a career as a data analyst or data scientist - Tomi Mester is a great teacher and everything is broken down in a way that makes it so easy to learn!

The JDS class bring concepts to life and in a format where you can grapple with technical concepts. The approach to data analysis is practical and will serve as useful tools in your career. It was challenging, but guided enough for me to follow and learn something in every session in order to level up my skills working with large sets of data.

This course provided me with a lot of insights about the necessary coding skills as well as the business thinking which every Data Scientist should have!

I had The Junior Data Scientist's First Month course, given by Tomi Mester.
All of the lectures are practical. Great, and helpful resources in Sql, Shell Scripting, and Python. Also google spreadsheets.
What I liked the most of his course are the course is project based. It takes you through from zero to get a project done, and work with big-data in bash.
All parts of the course were helpful, but I liked Sql, and bash parts so much.
Also, I want to emphasize that whenever you have a problem, Tomi is there to help. He puts his time for the course, and people who take the course.
I totally suggest this course to people who are interested in data scientist role, and who want to learn sql, and bash.

I enrolled in Data36's Junior Data Scientist course in 2019. That was very helpful for my budding Data Scientist career; in it, the website owner, Tomi, takes us through each step in a complete data analysis task, both the boring ones (data wrangling) and the exciting ones (machine learning). In addition, there are several highly useful articles about aspects of data science on the website. Overall, I highly recommend it!

I have been on and off with a number of online data science courses, I came to the JDS course because I wanted to understand how much I know and how much more I need to know before I start looking for internships or change of position in my company. The 6 weeks of the JDS was full of fun, doing things that I didn't know were important before, I learned some things that I never knew I needed but also I had a good chance to practice things that I already knew. I recommend this course to anyone who is serious about data science and most importantly those who are trying to start Junior data scientist roles
