SS stands for strength of schedule ranking, with $1$ being the most challenging.

$L$ is the number of losses during the season.

CA $($Computer Average$)$ is the average of computer rankings from various sources.

QW $($Quality Wins$)$ gives a measurement of the number of victories over highly ranked teams.

Find a formula for the $2001$ BCS ranking. $($Instructions: What you are expected to do is choose the data from $6$ of the schools to form a system of $6$ equations in $6$ unknowns $x_1,x_2,$cdots,$x_6.$ Normally one might think the best idea would be to choose the six top schools but if you try that it will not work because the coefficients for the $x_1$ and $x_2$ are the same for each of the six schools, and thus Gaussian Elimination leads to $0=1,$ which is absurd$.$ So use the first five schools and Washington and you will be able to obtain a unique solution.$)$
