What do you teach? I used mine all Spring and I may have loads of great tips for you.
I teach physical education....I'll be using mine mostly for grading, attendance, lesson writing ,etc...I also have an iPad Mini because the anatomy apps on there are much nicer. I prefer Android but I had to get an iPad to teach muscle anatomy & heart anatomy. But I had to buy the VGA adapter to hook it to my projector.
Any ideas you may have would be appreciated!!!
