It is seriosly useless to use ready made notes
You must make them yourself
If ur lacking time....Then dont try to decorate your books by keeping them as cleaner as u cud cz you're nt going to exhibit books after exams....Cm on get sm lyf and plz plz plz add as much as you can at your books.....they will help you out
by writing minutely n making points u ll find more time to work on and less time to waste.....That's wt i think
