@roshan: frankly speaking it totally depends on cae how much time they want to take
during the may session everything got over from written to interview results in 12 days
but from june onwards they started delaying and now its taking around 1 month for everything
another thing is they dont take any sim test but your sim test will be conducted after you do your type rating
also the best thing is you get your results for written on the very same day
so atleast if you pass your written then you will be given an estimate as to how many days youw ill have to stay back and accordingly you can extend your trip
hope this helps
