Questions related to CBSE Class 12th
On Question asked by student community
Have a question related to CBSE Class 12th ?
Failing in pre-board or selection tests does NOT automatically stop you from sitting in the CBSE Class 12 board exams. Pre-boards are conducted by schools only to check preparation and push students to improve; CBSE itself does not consider pre-board marks. What actually matters is whether your school issues your admit card. Some schools may pressure or warn students who fail multiple subjects, but legally they cannot detain you just because of pre-board results if your attendance and internal requirements are completed. In most cases, schools allow students to sit for boards after extra tests, remedial classes, or a written undertaking from parents. So don’t panic—but also don’t be careless. Use this as a wake-up call and seriously work on weak subjects instead of relying on hope alone.

Hello,
No, it’s not true that GSEB (Gujarat Board) students get first preference in college admissions.
Your daughter can continue with CBSE, as all recognized boards CBSE, ICSE, and State Boards (like GSEB) which are equally accepted for college admissions across India.
However, state quota seats in Gujarat colleges (like medical or engineering) may give slight preference to GSEB students for state-level counselling, not for all courses.
So, keep her in CBSE unless she plans to apply only under Gujarat state quota. For national-level exams like JEE or NEET, CBSE is equally valid and widely preferred.
Hope it helps.
