Hello,

Hope you are doing great.

Answering to your question, The term "NTA Score" refers to the National Testing Agency Score, a standardized metric employed to assess the performance of candidates in diverse entrance examinations administered by the NTA.

([100 - P] / 100) * N + 1

Where,

• N is the total number of students who have appeared for the exam;
• P is the percentage of students below or equal to your marks;
• (100 - P) is the percentage of students above your marks;
• ([100 - P]/100) * N+1 is the number of students above your marks.

Hope this helps!!
