Hello aspirant,

As per your query, you have said your percentage is 68 in pcm but not in total. So first of all your overall percentage in all the subjects is necessary for taking admission in NITs and IITs.

Before 2020, NTA's eligibility criteria for NITs and IITs was to get minimum 75% in 10+12 board exams. But because of the COVID-19 pandemic period this criteria has been removed by NTA. This criteria is still removed for 2022 jee exams but there is not any official notice by NTA informing that it will remain unchanged for the year 2023 whether they remove or not. So you have got all the points.

We hope this helps you :)
