My son is the exact same way w/ timed tests. He was fine doing them initially when we first started them in RS D. But afterwhile, he stopped wanting to do them. Now a sheet that would have taken him 5min, he will take 15min to do it!!! I even bribe him but it's almost like once he decided he didn't want to do it, even though he wants to do it now, his brain won't let him lol. Part of it for him is he doesn't like to write. I notice when we're playing games (no writing and no time pressure) he is much quicker with his facts.
