What is inside

The syllabus of this course is still being written, so there is nothing honest to list here yet. Buying it now is a pre-order: you pay once, and every module published later lands on your account at no extra cost. If you would rather wait and see, the subscription opens the whole catalog month by month, and you can leave whenever you like.

What you get

  • Lifetime accessBought once, yours for good — or included in the subscription.
  • Every future lessonNew modules added to this course appear on your account, at no extra cost.
  • Progress trackingLesson by lesson, on every device you sign in from.
  • Quizzes and labsChecks at the end of each module, and exercises to run yourself.
  • Verifiable certificateIssued at the end, with a number anyone can check from its page.
  • Written, not filmedText you can search, copy and re-read — no video to scrub through.

Who it is for

This course is written at a Advanced 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.
