Colleges accept the highest sub-scores from different administrations. So if a student takes the SAT many times instead of once, she has a larger pool of scores from which to pick out the highest math, critical reading, and writing.

Tutoring follows the lucrative philosophy of advertising: if you can manufacture a need, people with disposable resources will find ways to fill it.

The fact is that the College Board's products - the SAT, other standardized tests, the accompanying strategy guides - are sold at far higher than the cost to make them.

Pick any scientific field, and you'll find that those snubbed by their communities, left feeling alone and despised, were often those on the forefront.
