<p>I keep reading about different strategies on "bubbling." Some feel that it is better to bubble the answers as you answer them, while others feel it is better to just circle your answer in the test booklet and then, in the last 5 mins or so, bubble all your answers.</p>
<p>Which is better? And will proctors care? They always warn that they will walk around the room, seeing your progress. If a proctor walks by as I'm bubbling answers, when he just saw my answer sheet being blank 5 mins ago, will he care?</p>
<p>Most of the folks I have observed bubble by the page. They circle the answers to all questions on a page and then bubble on the answer sheet before turning the page.</p>
<p>Bubble as I go. Honestly I don't think it makes any difference.. if 1 second of bubbling makes you lose concentration, you have poor concentration :)</p>
