Dear parent,

BITSAT - one of the most national reputed exam organised by BITS (BIRLA INSTITUTE OF TECHNOLOGY AND SCIENCE) for admission in undergraduate courses in bits pilani, bits goa and bits Hyderabad. It is a very good college where many rank holders of jee advanced take admission.
And the difficulty level of bits exam can be compared to jee advanced.

As your son got 318 in bitsat then he can easily get any campus of his choice,
But your son hasn't passed the class 12th eligibility criteria so even with this much good score in BITSAT he can't get any of the bits campuses.

Because for getting BITS Pilani, BITS Goa or BITS Hyderabad candidates must have to pass their class 12th exam with at least 75% aggregate score and your son has got 72% in class 12th. So it is not possible to get admission in BITS Pilani, BITS Goa tour in BITS Hyderabad even with this much good score.
Also with this much jee advanced rank, he cannot hey any iits.
