Way too hard

This is called "Are you smarter than a "5th Grader". You show me a 5th grader that can answer these questions. It should be called "Are you smarter than a college student". Most of these questions are too hard. I got this game for my son who is in the 4th grade and he cant answer a lot of the questions. He hasnt learned half of this stuff yet. Where do they get these questions from? Plus, the "Solo" player jumps from grade 1 to grade 4 in one question.. Thats not typical of a normal player.
