Is there any way I can take a Microsoft online course on my iPad?
Maybe an app or something?
If its working with word, excel, etc no you cannot. Some classes have you do work on the programs and submit a finished product. Sorry if thats the case.
I did some work for a computer class last year. It was all online tutorials etc. You went though the tutorials online(fake access or word) and didnt need the programs on your computer. That I could do, but it was flash player. I had to download a flash browser(puffin) and it worked. With this case YES
