can anyone explain , what is tie breaker ?
Very interesting question! When the merit list is published for NATA, every student is given a unique rank based on their overall marks. A tie-breaking logic has to be applied when more than one candidate gets the same overall marks. So, who gets the higher rank is determined by the following parameters in the same order of priority -
1. More overall marks obtained in Mathematics test component
2. Less wrong answers in attempted ones of Mathematics test component
3. More overall marks in problems of Aptitude test component
4. Less wrong answers in attempted ones of aptitude test component
5. Earlier date of birth
This was the logic applied for NATA 2017, it probably hasn't changed that much for this year. Its similar to IPL matches when more than one team has the same points, the net run rate becomes the deciding factor to making the playoffs.
