A closer look
You are essentially just a walking, talking pile of office supplies waiting to happen. The human body is composed of about 18% carbon by mass, making it the second most abundant element in you after oxygen. If we theoretically stripped away all the water and squishy bits, the remaining carbon in your system could easily be compressed into the graphite needed to fill 9,000 pencils. So yes, you are technically very good material for taking a standardized test.
