kajal an 89 is very good grade, don't be nervous about it.
Even if schools had an 89 cutoff to interviews, they'll still need to at least interview below 90's people for several reasons.
People with 90+ get accepted more places, and they can only attend one, so they will withdraw acceptances from some of those extra schools. Leaving behind the withdrawn schools with a empty seat, that an 89niner (like you!) will go ahead and fill.
And since schools know this based on experience, that's the reason they interview so many people, and waitlist a bunch of them, 'cause they know eventually will need the waitlisted candidate to fill in a space.
Some candidates are upgraded to accepted from a waitlist even after school started, it depends how long accepted candidates take to reject the admission.
On the other hand..... Kajal are you from India?. I ask 'cause I see (rather read😛 ) that people from there worry too much about getting 90+. You guys have no idea how lucky you are you score upper 80's.
Among us things are not quite like that. I talk 'cause I've seen many people take this test and fail over and over, and then pass it with low scores.
So stop thinking about an 89 as a low score, and turn around your score report and check that you've managed to get yourself into a very high percentile. Good luck! 🙂
