Answer 1

Yes — you can use a single QR code for all your students. The trick is to have the one code point to a shared destination (a class page, a Google Form, or a folder) rather than encoding individual student data into separate codes.

A clean way to set it up:

1- Decide what the code should open — a class portal, attendance form, shared notes, or a registration form

2- Create that destination first (a Google Form works well for attendance or sign-up, and it's free)

3- Generate a dynamic QR code pointing to that link, so all 30 students scan the same code

4- Print and display it; if you change the linked form later, the same code keeps working

I used QRLynx for the code itself because the free plan supports dynamic codes and shows scan counts, so you can see how many students actually scanned. A dynamic code matters here — if you later need separate info per student, you can branch the linked page without reprinting. Quick tip: if you want to tell students apart, have the Form ask for name/roll number on submit rather than making a code per student — far less to manage for a class of 30.
