<p>Well, I needed the above so I created one in Excel. If you are interested, post a reply here and then PM me your email and I can send it to you. </p>
<p>How it works:
Basically, it is divided into flat scores and score ranges. To get your ranged scores when you have a flat score (e.g. 700), subtract 30 for the low end and add 30 for the high end. This should be an accurate range of your ability. Likewise, if you have a range and want to convert to a flat score, just take the middle of the range, for example the flat score from 670-730 would be 700. </p>
<p>Make sure to read the instructions and blurb on Flat Scores and Ranged scores (the one i just wrote; "How It works"). </p>
<p>Hope I could be of help!</p>
