TN Board 12th Class Biology Syllabus

The Tamil Nadu Board Class 12 Biology Syllabus has all the required components for a great foundation before the students can choose engineering, medical, or other academic courses. The board has adopted a future focus curriculum so that the topics are included in the syllabus before they are in demand in the industry.

Biology subjects lose their meaning if experiments and practicals don’t go hand in hand with theory classes. To this extent, the TN board has included a right mix of practicals in the syllabus so the students can also gain application perspective.
