So I have a blank scantron too. You just need to fill in your JET Number and your name on the form and which level you're doing.
Stick it in the envelope that you got with the pack and put your details on the back of the envelope.
At the very least, if they have your JET Number, they'll know your BOE who will be able to get the results or anything to you.
I would suggest that the study guide is a bit out of date in this section and they've put the blank sheet in there to make it clearer to people that it IS in fact the answer sheet. xD
I'm doing Online submission though, so shouldn't be a problem for me. As for the helpline hours, I haven't had to call them yet so not sure. I just emailed them.
