Hi, I have a minor problem with my ipad. All of my teachers post their slideshows online, but I can not figure out how to download them onto my Ipad. Is there an app I should be getting that will allow me to save these powerpoints to my Ipad? If so, is there one that I can use a stylus and take notes onto the slides? If this is something simple that has been addressed, could someone just send me the link please? I tried the search function with no luck. Thank you.
