DD took a basic calculator with her when she took the EXPLORE. We had to show her how to use it, since at that time she had only played with one, but not technically used one. She ended up not using it. I believe they specifically mention somewhere in the paperwork that it can only be a basic operation type calculator.
As for scratch paper - we brought some, but our testing center provided some and I don't think she used that either.
We brought along some snacks and drinks so during the break she could "re-fuel". She kept one water bottle with her in the testing room and we had extra if she needed it.
