<p>I’m willing to accept that crazybandit is the authority on the official position of CB on usage, since it’s been a long time since I looked at that material. </p>
<p>On the other hand, I am the same age and fussiness level (very high) as a lot of the essay graders. The use of “hopefully” when you mean “I hope” would grate on my nerves, and make me less forgiving of any subsequent errors, regardless of CB’s official position. I think it would be better to avoid this usage, if you can.</p>
