I have only one advice...be fast, send it the very first day, all in one...the certificate and pay the money...and send the confirmation via email (I guess you get it back...but not sure since I got in...).
Norway is quite unusual on Defi so you do have quite some chance to succeed. Important it is to let the Defi team know, that you really are interested...there is many people wanting to go, but some of them have a special fascination...and if you prove to be one of them I think the spot will be yours.
But of course there is no guarantee...
Maybe I just was lucky and I wont be this year...but for sure I will try to get in again.
PS: Lancellin is also great, but for europeans a bit far reach...:-(
