You can technically could re-sit for your 12th grade exams to change your stream from arts to science, it's generally not considered the most practical or efficient way to achieve your goal, especially if you're already in the final year of your BA Honours Psychology degree.

Most universities allow students from any undergraduate background to apply for a Master's degree in a relevant science field, like a Master's in Clinical Psychology, which would align well with your BA Psychology background and allow you to focus on the science aspects of the field.

If you still want to do science then go for nios exam they provide all subjects exams according to students needs but again i would say its a complete waste of time and effort and could delay your career plans.

After clearing the 12th grade, you cannot change your stream from Arts to Science. The foundation subjects and practical experience for a science degree are normally set during the 11th and 12th grades.

But, you may opt for these alternatives:

Undergraduate Certificate or Diploma Courses :

Contemplate certificate or diploma studies in science subjects that you find interesting. These can be seen as a foundational education to the subject, and most of them will get you ready for deeper study.

B.Sc. IN A RELATED FIELD:

Contemplate bachelor programs which involve sciences along with humanities. Examples include

B.Sc. Psychology: These usually cover courses in biology, statistics, and research methods.

B.A. Economics major with specializations in Econometrics This has to do with statistics analysis and modeling of data.

Self-Study and Online Courses:

Online courses acquired from Coursera, edX, and Khan Academy while learning science independently.

Don't waste your time by watching education videos, reading your textbooks, and solving problems for a strong foundation.

Career Counseling Services:

Seek services from career counselors in consulting alternative careers that you are interested in and possess requisite skills for.

Remember that, indeed, taking up a different academic course after the 12th standard can be difficult; however, it is by no means impossible. All the right planning, along with all dedication and willingness to learn, allows you to still achieve your academic goals.
