Hi,
I am sorry to inform you but you are not eligible for BITSAT. According to the criteria, a student should score a 75% aggregate in physics, chemistry and maths.

But since you have got the hall ticket you can visit once and see if they allow you to just sit in the exam. But you won't be able to get admission in the college.
HOPE THIS HELPS
