The half- yearly and quarterly exam for every class is very vital for the final year exam. The course structure and number division helps students to build the correct strategy for the final examination. Following the TN- state board mathematics books correctly will help the students to have a clear understanding of the subject.


The TN board has followed a standard syllabus pattern. Following the TN-board class, seven science syllabus topics will guide students to make a routine for the exam. Science is an essential subject for the future career prospect for class 8 students. TN class 7 science syllabus follows the course structure of CBSE to make students globally competitive. Students must understand that studying science opens many doors of career opportunities in their later life. The transparent marks distribution guides students to give proper weightage to every topic. TN board is effective enough to choose suitable topics for the class 7 science syllabus.
