The attachment below is Angel Notes as termed by Cid. It was circulated in Ateneo COL. I presumed its meant for sharing so I'm offering it here for view or download. The credits are all in the PDF file itself.
If ever I was wrong and this does not belong here please contact the admin and we will undergo the necessary process (removal) and blame it all on Cid hehehehe. Thanks to Angel and the person who gave me this Cid. Good luck on your studies, Sharing is good karma.
