Replying to Fake doctor notes for school +K for help

Ok so at my High school if you have over 7 absences you need to get a 77% on the final exam to earn credit for the class. So its my senior year and yes I do have over 7 but didnt realize that I am over until now. I have a doctors note saying that I was with them for one of the days but I need 3 days excused and that one is only for 1 day. So im pretty sure there is a way I can scan that paper onto the computer, make 3 copies of 3 different days and blank out the docs sig and just forge it myself. Im not a computer expert and maybe to some of you this would be very easy.


Long story short I have a doctors note and need to make 3 copies of it with 3 different dates so i dont need a 77% on my algebra 2 exam to pass the class and graduate

karma for the help
thanks
