urgent GMCS registration - pls help

Please help urgently!

I want to register for GMCS batch in Mumbai,

for december month batch.

Can i register it from advance i.e this month June 2010?

i dont want to take any risk as GMCS batches are not conducted for more than 50 students per batch.

so can i register and secure my place in december batch from now itself?

is it permissible by icai or allowed for such advanced registration?
