There are many ways to "pronounce" (articulate) this sign.
All of them focus on the concept of showing a type of "question mark."
This generally is shown by a straight index finger changing into an "x" finger
while moving downward as if drawing a question mark in the air.
TEST:
Version 1: This version of the sign TEST starts with index fingers
straight, then bends them into "x" handshapes as the hands move downward. Then
the hands change into palm-down "5" handshapes.
Quiz:
This version of "TEST" starts with index fingers, moves the hand downward and
changes into "x" hands, holds for a brief moment, changes back into straight
index fingers and moves down a bit more while changing into "x" hands a second
time.
