After finishing the 40hrs do the 'Flight Test' with the A cat, ask him to sign off the form (Link above)....This is your check ride....Keep the report, you need to submit it at DGCA
You dont have to do the check ride in India after this.
Just get a certificate from your academy saying 'Sarin has completed ground training of 20hrs on P68/duchess'.....thats the equivalent of the techinical paper, you dont have to give any exam in India....
