You may get admission in BSc.Computer Science with this Score in your board. The possibility of getting admission in not much as the Admission there is duly based on the merit list prepared by colleges 

If you are interested in taking up a course in Mumbai then these marks can get you an average course but if you opt in for some entrance exam then that would definitely not get effected by these marks. Entrance exams play a major role for students who haven't scored well in boards .

Try your luck

All the best
