Physics Practical Exam Guidelines for 2022-23 by SCERT
┗➤ Download Published@23-11-2022 

A minimum of 14 experiments must be performed by each student with at least 7 experiments from each section A and B (First year and Second year)

Physics Practical Log Book
The experiments performed by the student must be recorded in the logbook. The student should be encouraged to draw the tabular column and write the aim and principle of the experiment before performing the experiment in the lab and the certified logbook should be submitted for practical examination. A single logbook should be used for the first and second year. A minimum of 14 experiments should be recorded in the practical log book.

NB:- "Performing experiments using the same apparatus/principle and recording them as different experiments should be avoided
Eg. (i) Find the volume of a given sphere using Vernier Calipers and (ii)Determine the density of a rectangular block using Vernier Calipers cannot be recorded as two separate experiments"
