How can i improve my 12th marks while doing btech to get eligible for most of the companies for on campus placements
Dear Aspirant,
You cannot improve your 12th marks if you haven't applied for improvement in the passing year of your plus two. You cannot apply for improvement exam after the passing year. So if you are in final or prefinal year of your Btech, then you have no option to change your 12th marks.
I suggest you should more importantly Focus on your studies in BTech and your project work and skill set.
That will lend you a job for sure.
Hope this helps. Thanks.
Concentrate on future> Talk to your faculties about the same. They might be able to get relaxation in percentage criteria of some recruiters.
