Hello there,

Yes, you can pursue a new stream (like Biology) after completing your 12th in Arts. However, you will have two separate marksheets — one for your Arts stream and another for your Biology subjects. This is generally not an issue, but it depends on the specific course you want to pursue and the admission requirements of the universities you apply to.

Having two marksheets shouldn't cause any major problems, but make sure to check with the institutions you're interested in to confirm their eligibility requirements.

I hope this answer helps you. If you have more queries, then feel free to share your questions with us, we will be happy to assist you.

Thank you, and I wish you all the best in your bright future.
