Yes, it requires graduation degree in any stream with at least 50% aggregate marks.

IGNOU provides such courses too. Experience will be handy, if you can manage it somehow. Apart from that, you will have to study for the course too. That means you will have to give time anyway, so get some experience along too.

I am agreed with Vinayak's answer, but I would like to suggest you to have 2 years' experience before you join. Regards.
