Hi Falcon, as a teacher and student (again) that would definetly use a calculator tutorial if needed I hope you can use the following suggestions: 1) As stated above it would make more sense if you aligned the Home, Forum and Articles buttons on the same side. 2)You've got a lot of info on here is there any way to categorize better most students won't take the time to scroll through to the bottom. 3) Your font for the directions is totally overwhelmed by the screenshots maybe think about balancing them out (I know that is hard because we need to see the screenshots clearly maybe crop until only the relevant part is showing whenever possible. Most students would never use Ctrl function to change font size 4) I understand that you are probably making money from the ad links but the adchoices ad at the center is exactly where your eyes goes as soon as the page opens which makes it look cheap or like a bogus spam page. Also, all the blue hyperlinks at the top center are very distracting can you maybe bullet them to the side? Hope all this is not to negative I like the overall purpose of the page and hope you can use any of my suggestions!
