Will I get admission into mechanical

Basically i got 127/200 in my net 2 with 0 prep and i have an o level equivalency of 86% im currently in a2 so my a level grades wont count. My aggregate is coming out to be 69.13 and the merit calculators say i have a 73 percent chance but ive heard people saying its inaccurate so i was wondering if anyone whos studying at nust could tell me if i have a chance at nust h12 smme. im asking so i can maybe focus on my a levels if i already have a safe chance at nust

thanks in advance
