Query: Good reading which will make the student money.

Using my own risk/reward model as applied to the projected benefits of purchasing this investement vehicle in education, and specifically forcasting a student's return (as salary) "n" yrs from the date of his/her investment, I can determine:Given: n= yrs studying the text (assume 2); q= the IQ of the student (assume 120); c= inate charm factor, 1-5 (assume 3); w= probable inheritance (assume $15M); f= the propensity towrards fraud (85%);Then, doing the math:Salary = {[sqrt of f/(1+c/q x w)]n!}-3 = $85,436.52/year (until time of capture by police in 7.3 years for fraud)If fraud factor is assumed to be less, but inheritance factor kicks in sooner, no need to buy this book.
