Dear student,

The criteria for Bits is-

• Candidate should have obtained a minimum aggregate of 75% marks in Physics, Chemistry and Mathematics subjects.
• Candidates should have passed 10+2 exam from a recognized central or state board or its equivalent.
• Candidate should have minimum 60% each in Physics, Chemistry, and Mathematics/Biology.

As per your query it is a waste of your time and efforts to prepare for the bits exam if you don not meet the basic criteria to sit in the exam. There is no change  in this criteria.

Hope it Helps!
