Note: (A)
Every student will perform 12 experiments (6 from each section). The activities mentioned are for the purpose of demonstration by teachers only. These are not to be evaluated during the academic year. For evaluation in examination, students would be required to perform two experiments – one from each section. The report of one Activity should be submitted at the time for Examination.
