Hey there,

Hope you are doing well and keeping fine,..

So heres the answer to your query..

See dear, getting 57 % marks in 12th board exams are not good at all. You should really aim higher provided if you want to secure a seat in a good college that too in a good branch. Hence you need to score a minimum percentage of 80 % and above to get admission in a good college. And board exam marks matter only incase if you want to take up just honours course for graduationor else for technical line for career pursuing then you surely have to give the respective entrance exams for the respective career paths.

Hope its clear to you..

With best regards..
