I just got an e-mail from Lumin PDF revealing that all of the premium functions are now readily available to instructors and their trainees for totally free! The premium features include combining and splitting PDFs, highlighting (in addition to the normal annotating options), and the elimination of banner advertising. And Lumin PDF incorporates with Google Classroom. You can sign up for a totally free Lumin PDF premium account here..

Lumin PDF is a neat tool that I blogged about a number of years ago when one of my associates required a method for her math students to make use of PDFs that she sent out to them in Google Classroom. You can read
more about that scenario right here..

If youre interested in other alternatives for annotating PDFs, I recommend attempting the tools built into OneNote or trying Kami. Video tutorials on how to use both of those tools are.
readily available here..
