"Class X"

Well, what have we here, if not yet another "expert". At the ripe age of 23...

Could someone enlighten me as to what this "Class X" is all about? Must really be something special to make this "mad boember" an x-pert!

Story:
India -- A month before the Republic Day, the Delhi Police has arrested three alleged Lashkar-e-Toiba militants. Police said the three hail from Manipur and had come to Delhi with the intentions of carrying out bomb blasts in the market areas here.

Karnal Singh, Joint Commissioner (Special Cell), said it's the first time that the police have arrested Lashkar militants hailing from Manipur.

Of the three men arrested today, 23-year-old Salman Khurshid is the most important, said police. Khurshid was a resident of Imphal and had studied up to Class X. An expert in karate, police said.
