how to prepare practical files such that i score 30 out of 30 in practicals..... I have taken phys. Edu. along with pcm

make sure that all your practical subject files i.e. physics, chemistry, & physical education are neatly covered. label all the diagrams properly and on 1 side, also write the Aim and other required points neatly using 2 colors black and blue. Make sure your content matter is absolutely correct.
