<p>For those that do not look behind the number, 2230 is a loss of 170 total points. In the range we are talking about, especially where 1 wrong question means the loss of a quarter point, which can mean the loss of a full raw point (by taking you to a .75 from a .50) as well as the loss of the raw point for the question being answered incorrectly, we are talking about possibly the difference between a straight 2400 contrasted with a 2230 being as little as 3-4 MORE answers being incorrect. On a 4 hour exam. With 170 total questions. And an experimental section.</p>
