Anyone who has taken a standardized test in the last say, fifteen years knows what a Scantron is. This convenient sheet allows tests to be graded very rapidly and very efficiently. The problem is, when they designed these, they didn't think about the effects that it would have on people like me.
You see, when any serious test is given using these (SAT, ACT, I imagine the MCAT, LSAT, and GRE as well), the person proctoring the exam has to read instructions on how to fill out one of these. They tell you how you need to fill out the bubble completely, darkly, and within the lines. This is something that I would have done with or without the instruction. The point of this is, it take A LOT of time. I would say out of most tests that I take, a solid 25% of the time I am filling in those ridiculous bubbles; carefully tracing the ring, meticulously filling in the center so there is no spill-over. And don't get me started on when I have to erase.
Scantron, I think you are an amazing product. You truly have revolutionized testing. But though I think you are amazing, me and all the other people in the world who might happen to only leave the radio and thermostat on certain numbers, who reload the dishwasher almost every time they start it to make sure everything is in just the right place, who automatically straighten their shot glasses when they are put into the rack off center, we hate you. Curse the day you were created.
