It is okay to be indecisive on the route to choose for your application. Believe me, I was also surprised to see many March and April applicants use the online route whereas Jan and Feb online applicants have not received AOR's compared to their paper route counterparts.
As I mentioned in my previous post, neither the paper nor the online route is perfect. But having said that, I think people are still using the online route because more of the online applicants have received Test Invite after AOR compared to the paper applicants that have received AOR. In addition, it is easier to handle than the paper route (not a great pro!)
So, the big question is whether one prefers to get AOR faster without moving to the next stage for a long time than get AOR much later but subsequently receives faster processing. This was what we observed from the early Dec. online applicants. Nevertheless, will that continue? Who knows?
