Have you looked at the sample questions for the Explore? That might give you a better idea about what the test is measuring.

That was a good idea. Ds had looked at the test booklet when it came, but it was more of a "look at this and see if you feel comfortable," kind of thing. I was more concerned that he wouldn't feel frustrated.

I'm impressed that you drove and stayed at a hotel. We had a bit of a drive, but not 1.5 hours (about 40 minutes) and ds is an early riser, so it wasn't bad at all. My only concern was that he gets carsick very, very easily (sometimes driving to the high school 20 minutes away).

And my ds has never seen NOVA- but I bet he would like it, so you've given me some good suggestions!
