I want to teach N8N to a group of 40 students. I’ll be teaching a group of 10 students.
Do they all need laptops during the lesson?
The server fee is very high, and the exchange rate in our country is also very high. It’s difficult for me or the students to afford this. What do you recommend?
My goal is to teach N8N to the 10-13 age group, and I’m open to your suggestions. I’m learning and implementing steps for the 14-16 age group.
You can teach n8n at a very low cost, but what cost are you exactly referring to? Tutorial fees that your students will pay you for or n8n hosting or cloud hosting fees or all of the above?
As for hosting, you can host n8n for free locally on each device (laptop or desktop), using either Docker or CMD (as Administrator preferrably). This is the best option for teaching, learning and experimenting purposes. This also answers the question if your students need laptops or desktops. The answer is YES, for emersive hands-on learning (getting their hands dirty if you want to think of it that way). I teach automation to primary and secondary school kids in public (government) schools for free here in Nigeria as a part of my CSR, and this has been my approach. But the schools have computer labs and we schedule different students for different days on the timetable.
Will you and the students be in the same location?
Do you have access to one or more computers?
Do you (NOT THE STUDENTS!) have administrative rights to the computer?
on a computer that you have administrative rights to, install Docker or docker desktop
Windows/Mac = Docker Desktop
Linux = Docker
Do no give administrative rights to 10-13 year old students!
I cannot state this strongly enough!
Ask me how I know 
install the n8n docker container
on the same computer or different computer on the same network, connect to n8n with a browser
Teach the students
I can give you no help with this. I would like to know how you survive teaching more than three 10-13 year olds for more than 5 minutes.
For that matter, I’d like to know how to survive three non-student 10-13 year old family members for a visit of more than 72 hours.
