I agree with all the other posts. As far as I know there is no rule that you only get one shot, either you send in the good stuff and it's a yes, or it's a no and you are out of luck and that's that!!
In our case, we sent a portfolio and qualifying IQ scores. I obviously didn't know what to send because they went ahead and asked for the achievement test.
I'd guess they'd let you know if they wanted more info.....
I'd stronly agree with Dottie that any tests, like cogat, that aren't actually on the list could be considered portfolio.
My 2 cents! Good luck.
