do i have to appear for all subjects in improvement exam in 2025 my percentage is 74.8 i only need 1 mark . if i appear for 2 subject will my old marksheet be valid . if i score less than before what will happen?
You can give improvement exams in subjects according to your choice but note that 75 percent in PCM is compulsory to get into BITS but this is not compulsory for admission in IIT. it will not only help you for admission in IIT or BITS but it lands you in a safe zone and if you are comfortable than give for all subjects.
