This is a bad idea. You would just be creating another layer of gerrymandering.

I won’t call out of or the drawer for bad idea. The idea is fine. There’s just zero ways to ever implement it. It’s nice to dream though

Uhh, no the idea is most certainly not “fine”

It’s only fine if you don’t think about it at all beyond the surface level presentation.

The concept that only the educated should vote is essentially the entire advantage of living in a republic. If the test was actually fairly made it would be fine, the real problem is it would be used to limit specific demographics from voting while not actually ensuring only the educated can vote
