If it's about the admission process where the score of 10th and 12th is taken into consideration then there's nothing known as a definite calculation, especially for the 10th and 12th marks.
Like most colleges, NITIE follows a decent distribution of the marks. The distribution is as follows:
| Particulars | Weightage |
| Entrance Exam | 25% |
| GD / PI | 25% |
| Graduation | 20% |
| 12th Exam | 20% |
| 10th Exam | 10% |
This is the following structure for the admission process by most colleges. The only point which can differ is the reservations. Rest everything remains the same.
