You might be qualified if SNU Noida only takes into account your overall board average (69%), but you won't meet the requirements if they demand 65% in PCM, which is typical for BTech.
The website does not specify OBC-NCL relaxation. To find out if your PCM score is acceptable or if there is a relaxation for OBC-NCL candidates, it is best to get in touch with SNU Noida admissions directly.
Requirements:
• Your PCM is 61%, which is below 65%, but your board aggregate is 69%, which is higher than the required 65%.
• Although 65% in PCM is also required by many universities, eligibility for a BTech is determined by the total score rather than just PCM.
• If PCM must be 65%, you do not meet the cutoff, but if only the overall board aggregate is taken into account (69%), you might.
• Official sources for SNU Noida do not specify OBC-NCL relaxation.
