So I am reclassing to a paralegal specialist 27D, and one of the requirements is to take a speed typing test. Does anyone know the link/web?

Your installation's education center can proctor one for you. They'll stamp it. That's what I've used for Soldiers before- works just fine.

Any will do, but once you get there, they will have you go to one on their computer and have you do it, they are pretty nice about letting you get multiple attempts.

There are several options in Google, but I am not sure they would be accepted as they are not proctored.
