Who it is for

This course is written at a Intermediate level, in the Data track. You need a computer, an internet connection and the willingness to type the commands yourself — everything else is explained as it comes up.

Before you buy

One-off purchase or subscription — which one?

Buy the course if this is the only subject you want: you pay once and keep it for life, even if you never come back. Take the subscription if you plan to work through several courses this year — it opens the whole catalog for as long as it runs, and stops opening it the day you cancel.

Is the certificate worth anything?

It is issued by us, not by a university, and it says exactly that. What it carries is a number: anyone — a recruiter, a client — can type it into the verification page and see the course, the date and the holder. It is proof that the work was done here, not a diploma.

What if the course is not for me?

You have fourteen days to ask for a refund, by email, without explaining yourself. The card is handled by Stripe and never touches our servers.
