Hi Niraj!!! As you mentioned you're already in BCA 3rd year so I would like to tell you that you shouldn't worry or think about what has already happened because it is out of your hands now. So, I would like to suggest you to focus on your career goals and work hard for that so that class 12's 46% doesn't come in the way to stop you.
Hope that helped.Thank you
