License requirement for Bookings with education package

Update:

I received this message:

"Hello, I read your post about the booking system for education, I wanna ask you, in the end you can solve this issue, I have the same question, i have A1 for faculty and student, but i want know if only one people can have A3 for faculty or we need have A3 for alls teachers."

Answer:

Yes, I solved it. After talking with Microsoft, they said we can upgrade a limited number of licenses to A3 - we do not have to upgrade all the teachers' licenses. This is a good solution.

In our case, the university is now deciding whether to buy the A3 licenses for all teachers - so it is going through the administrative process - I'm still waiting!

Extra note:

I did try a 30-day trial version of the Business version. I like the Booking system, but of course, it cannot join to the university contacts list/network - which is a good thing for security, but this doesn't help in my situation.
