hi reader ,

In BITSAT ,Admission to all the programmes is subject to the conditions given below:

• Candidates passed class 12 or equivalent examination (from any state/central board). However, they have to score 75% aggregate marks in Physics, Chemistry and Mathematics/Biology in the qualifying exam. Also, in each of the 3 subjects, they must also secure 60% marks separately.

since you have 74.3% you are not eligible . You can wait for this year's criteria to release as it may be relaxed because of covid. alternatively , you can mail the authorities regarding your concern and they may further help you

i hope this helps

thanks you
