Ipcc itt & orientation programm

it is not compulsory to complete both on the same time...  may ITT first... or may orientation first.. there is no issue  regarding  this.!  but both should be completed before your exam attempt due... othewise u should be treated as Provisional student for the attempt. and will submit your ITT and Orientation certificate copy before month of result.!  

u should complete both before the date of result.! other wise ur result will not be out.!  

There is no order prescribed for completion. But its better to complete ITT first and then Orientation. As per latest rules of ICAI, both ITT and Orientation can be completed before joining articleship. So for now you can write exams without completing those and must complete both before joining articleship.
