894/what? It could be out of 10,000 (although that would be ridiculous). Besides, test scores show how much attention you pay in class, not your intelligence.
PhDs have an average IQ of 125. Neurosurgeons (etc.) have an average IQ of 135+. Geniuses have an IQ of 155+. And yet, you, the 14 year old, severely trumps all of those people with 172? HIGHLY doubt it.
