CBSE 12th

Hi there, I hope you are doing well. I feel you first need to calm yourself. Whatever happened is not a big deal. It happens with many people and you are one amongst them. You need not worry at all. I suggest you to reappear in boards to clear your subject. Just a passing marks will be enough to proceed further. There are number of good colleges and universities which gives admission in just 50%. You already fit in this criteria all you need is calming yourself to re-appear for clearing your maths.
Remember if you do well in your college by attaining good marks in every semester, performing in cultural activities, doing your assignments and internships sincerely, you have a long way to go.
Mass Comm. Has nothing to do with your 10th and 12th marks unless you have entered the college. Industry is only curious to see your qualities as a journalist and that includes impressive communication, Writing or camera skills. Worry not the media Industry is early waiting for you.
Wish you all the luck dear.
