Hello,

To complete class 12th Biology, schools will take whole one year along with conducting exams, practical and providing holidays. Schools take this long because they have to teach the topics comprehensively.

But for students preparing for competitive exams, they can prepare whole biology in less than one year.

To pass in 12th you need to score more than 33.3% together in practical and theory exam in Biology.

Hope it helps.
