Re-registering for Level 1; can I switch to Level 2 if necessary?

Hey guys

I’m scheduled to sit for the December 2011 Level 1 exam; but I must be realistic and feel I will not pass this one. I’d like to register now for the June 2012 L1 exam to sure my place at desired center. However if I would pass now in December, would I be able to switch registration later to Level 2 in June?

Hope someone knows!

Regards!

You will not be allowed to register for June 2012 exam until you receive your results for Dec 2011.
