Intelligent Tutoring System

This is an online intelligent tutoring system, wherein students can register and avail for tutorial services. Tutorial services are done in two ways, one is documented tutorials in which lessons are compiled in the database (MySQL) and the other one is using an Artificial Intelligence wherein students can ask questions directly to the AI System. The database of the AI are stored in (XML). Have fun with this old code of mine.. I just want to share with you guys.. You can vote for it if you want.. Thanks..
