Hello there,

Yes, you can pursue science after completing your 12th in the arts stream. Here's how it works:

1. Changing Stream : After 12th in the arts, you can apply for a science stream, but you will need to start fresh with subjects like Physics, Chemistry, Mathematics (or Biology) depending on your chosen specialization.
   
   

2. Marksheets : Your arts stream marksheet will still be valid, and you will not lose it. However, for science studies, you will receive a separate marksheet for the science stream.
   
   

3. College Admission : You can apply for a degree in science (e.g., B.Sc., Engineering) after fulfilling the eligibility requirements. Some colleges may have specific entry requirements, so make sure to check that.

You might need to clear an entrance exam or meet the minimum eligibility for science courses, but you are absolutely allowed to switch to the science field for higher education.

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 wishing you all the best for your bright future.
