NCERT
Dear Aspirant,
Hope you are doing well,
First, read the whole book thoroughly and then sum up all the points as per your convenience so that you can remember what I had studied, shorthand saves time as you had studied earlier and know the full meaning of short terms that you had made.
For the first time reading short notes will not help you, but reading the whole concept thoroughly will help, and reading after some time again as you may not remember the whole things after some time as our mind is not so sharp that it can remember the whole things.
Hope it was helpful and you get the point.
All The Best.
