Keep thinking outside the bubble, Robin. Scantrons are tools from the pit of hell & designed by mindless imps.

Back, way back, when I was in school, we did have multiple choice tests sometimes. But NEVER did we have MC tests for math or history like you do now. Lazy teachers! Unless it's a really well-written test which can actually be harder than an essay test. If you ever take the LSAT, you'll see! I heard nightmare stories from folks who took that.
