I've built one for the US Amateur Radio exam pools (which are public) as I'm trying to sit for both my Technician and General in the same volunteer exam session.

Mixing the questions between both pools and studying as a unit I've found has had two great benefits: 1) I'm not focusing on Technician first and then going for General as a "bonus" and 2) it helps me see the connections between the material.
