Hi, and welcome! Those are solidly GT scores, congrats!
One thing to remember about a DYS application -- even if you do portfolio, they'll want to see any scores that you do have, so you'd have to send them in. I'd recommend retesting, if you think those scores are way off, before sending in a portfolio unless you've got some amazing portfolio material (and you might!). I'd also call your tester and ask for percentile rankings on all the scores you were given, for your own reference if nothing else.
Good luck!
