This is the free/included "how to unpack and set up your printer" , how to start a print, how to print something from PrusaSlicer/Printables, and very basic introduction to 3D printing. 

You can buy additional "seats" of that course for $5.49   each. 

Kids went bananas over free programming courses on Android apps, some from google, to collect "certificates" , happily solving simple programming tasks and answering tests.  I just thought that was a cool thing to forward to them, and guessed that there could be some professional need that made Prusa already add this option. 

So this is not so much about how to acquire the knowledge, as "how to be able to share the course" (in a way where they can answer the questions themselves, and get the certificate.)
I appreciate all attempts to solve this, but I see that it does not seem to be possible, and is not a problem. It was "fun to have"

Happy New Year everyone.

This is the free/included "how to unpack and set up your printer" , how to start a print, how to print something from PrusaSlicer/Printables, and very basic introduction to 3D printing. 

the way I see it, making such course available to my kids will only give 3D printing more attention, and introduce them to Prusa ecosystem earlier.

This is a missed opportunity to Prusa to catch more user's interest.

I would argue it is just the nature of their pricing model. The price you paid gets you a single-user license. Maybe they should consider offering volume discounts if you buy multiple licenses for the same course, or a multi-user license at a higher price.

Edit: Oh, you probably did not pay any price, since this was a freebie that was included with the printer? Then, of course, you can always wish you had received a bigger freebie. But I guess it is what it is. 

This is a missed opportunity to Prusa to catch more user's interest.

Letting your sons use your Prusa account to access the course is probably the only way to go. Scout's honor that they will not order loads of filament or a new printer in your name! ;-) 

Or create a dedicated account for your sons, assign the course to that account right after purchasing it, and then use that account yourself if you also want to do the course. That would also let you print a certificate with the right names.

My sons (10,13y.o.) are not very into 3D printing, but I know that the "certificate" at the end is somewhat motivating :) 

How can I give them access to this course?

This question is highly related to: If I buy such printer for work, how can I give the course to more than one colleague ?

(there should be a way of sharing such a course.)
