It's difficult to get definitive and fully accurate information, as most reports are biased towards seeing him as a terrorist and with such bias, accuracy is automatically somewhat suspect. That being said, he's from a wealthy family. He went to University. He certainly appears to have studied economics and business administration and some encyclopedias have him listed as having studied civil engineering. That being said, without an "insider's biography" to compare with and without proper evidence to back up these claims, it's hard for us to know for sure. It's hard enough to get school records in the USA. I imagine it's just as hard elsewhere.
