Hey!
Different exams have different eligibility criterias , some can demand individual minimum 60% and some can demand collectively 60% . So, it all depends on the exam or college you are asking about.

Hello aspirant, hope you are doing good.

So, I'm assuming that you want to know the answer to this question based on the qualifications needed for NEET, so I'll answer it in that context itself. According to NEET guidelines:

• You are required to score at least 50% marks in Physics, Chemistry and Biology in aggregate in the qualifying examination if belonging to UR category. For reserved category candidates, it is 40%.
• You are also required to pass in Physics, Chemistry, Biology, and English individually in the qualifying examination.

Hope this helps you. Good Luck !!
