Hello student,

You have not specified any special subjects where you have been this.

National Institute of open schooling has already been uploaded their actual 12th level syllabus of all subjects in their official website.you can avail this also from our website as well.

But as per my view, I have checked the core science syllabus of physics chemistry biology and mathematics, I found quite  similarity of the syllabus with other boards. However some syllabuses are similar with 11 as well in part. Click on the link below to view the actual syllabus
