Hello,

The syllabus is not available online for 12th standard, If you can ask your teachers to provide you then that would be better way to get.  The official page of the board is not working properly to check whether there is available or not. if you can visit the page and download it then that can also be a way.

here is the link:- https://gbshse.org/

You can ask your friends too if they have the syllabus with them for the subjects.

for more details you can visit :- https://school.careers360.com/articles/goa-board-hssc-syllabus

Better to take guidance from your teachers with respect to subjects and study well. Give your best in the exam.

Hope it helps!
