i've got another [hot tip] or you today.
PDF'S are common files. You'll see them used all over in online teaching from
posters, to persetnations.
But these files can not be be edited by the receiver.
So what about when you want to provide some notes?
"marking up" PDF's is actually quite easy and
i'll prove it to you.
If you use Google Classroom, this trick will save you hours
of time and frustration.
