Rhce exam - karachi!

Hi guys,

I'm interested in taking classes at techno-ed for RHCE certification. If any of you have any experience in this regard, can you tell me what the official exam fee usually is? A ball-park figure would be sufficient.

From what I've heard, the exam takes place once a year in Karachi somewhere in Nov-December, political situation permitting. But what does it cost to take part in the exam?

Any help/advice would be great.
