Hii,

After completing 12th grade arts (English medium, RBSE), you can pursue a BCA degree. While many private colleges accept students in the arts, some may require math or computer as a 12th grade subject. Before applying, simply review the college's rules.

Since BCA is about computers, you should be interested in learning software and coding. Even if you have an arts background, you can succeed in BCA if you put in the necessary effort.

Hello,

If you took your RBSE Class 12 exams in March 2025 and wish to improve your scores, you can appear for improvement exams in 2026 . RBSE allows students to take improvement exams in all five major subjects.

The improvement exams are typically held alongside the regular board exams of the following academic year. To apply, you'll need to fill out the improvement exam form, which is usually released after the announcement of the current year's results.

Hope it helps !

Hello,


The Rajasthan Board of Secondary Education (RBSE) requires Class 12 students to secure at least 33% marks in each subject to pass. While RBSE has not officially detailed a grace mark system, it may award grace marks to students who are slightly short of passing marks, as per the board's rules and regulations. However, the number of grace marks is limited, and students should not rely on them.
