Let me think

I was doing a SAT practice test at home. I think it would be easy if it were in Japanese but, of course it is not Japanese and the tricky questions make me crazy. So, when I don't understand questions, I always ask my dad but he doesn't give me a time to think about it because after he explained it, he answers himself so after I hear his explanation, I always run away from Dad with the text books and do it myself. But, he doesn't like it.
