• Candidates applying through IAT channel have to sit for IAT - 2026 exam.
• Candidates applying through the SCB channel have to enter your subject-wise marks such as the name of the subject, marks obtained out of maximum marks.
• If a board provides aggregate marks considering both Class XI and Class XII, then only Class XII or equivalent examination marks should be considered.
• If a board provides aggregate marks considering the results of all three years of a 3-year diploma or courses of equivalent duration, then only the marks scored in the final year should be added.
• Subsequently, the marks obtained in the last two semesters should be mentioned for boards that follow a semester system.
• Suppose a board provides only letter grades without giving an equivalent percentage of marks on their grade sheet. In that case, the applicant must obtain a certificate from the said board specifying the equivalent marks and submit it before the deadline for the mark sheet submission. 
• In case the board does not provide such a certificate, the percentage marks will be assessed as follows:

percentage marks = (CGPA or CPI obtained × 100) / PS

             {PS is the maximum value of the point scale used by the respective board.}
