Ayush as per your marks it seems that you have very bleak chances of getting admission in delhi that too in cse.

I suggest you to fill in for improvement because not if 75 per cent, at least 60 per cent is required to get admission in a good college.

Also I suggest that alongside you can prepare for the jee exam. And then score good next year and grab up a good engineering college.

All the best for your future.
