Dude, I don't test well, I never understood the purpose of tests, I still don't, I think they're the biggest waste of time since the invention of the hula hoop, and I never developed the tact to mask my contempt for the damned things in front of the teachers who thought they were Very Very Important and would Determine The Course Of My Life. At this point, the idea of taking a test other than to test my vision or ability to safely pilot an automobile would make me reach for my crossbow.
I write books for a living. People read them. Test that, yo.
edit: obviously, Take The Big Multiple Test is different from a skills test, a la krav level. Those, I would do in a heartbeat, like the driving test.
School tests? No.
