<p>I can imagine this working very well for both test takers and the test makers. For one, cheating would be hard because you can truly restrict people going back to other sections or working on math problems in a CR section. It's a little quicker. Hacking shouldn't be a problem if you're monitoring them(and you can look at everyone's computer screen from one main administrator). I do'nt imagine people bringing USB flash drives to hack it or anything. </p>
<p>The best point of all: the essay! I type almost 100 words per minute and while I do write very fast, no one in the world can write in English as fast as me or any other fast typer. I type faster than I think, and I think faster than I speak. Typing helps me to get my words and ideas out quicker. When I'm writing, I can lose track of my ideas because it takes a while to write it all down. Much easier to edit essays, easier for essay graders to grade, easier to replace answers(MC and Grid Ins), and you can even get an instant score after each section if you want! You can always have the choice of taking the written portion, but I would never consider it!</p>
