Reminds me of the "Find a bug, win a Bug" promotion from Hunter & Ready Systems in the 1980s for their real-time operating system kernel.
Never met anyone who won a Volkswagen, though...
Google: Want to pony (or beetle) up?

My son is graduating next week with a Bachelor's degree in bioengineering. I would have suggested that he go on for a Master's, except that he got a job offer with a prominent company in his field that will contribute substantially to tuition for grad school. At that point, and in these financial conditions, he agreed that he should take the job and pursue the Master's while there.

Personally, I went immediately from undergrad (physics/math) to a master's program (CS/EE) both to dig a little deeper and to optimize my chances at Member of Technical Staff jobs with my then ideal employers, Bell Labs and Hewlett-Packard. Got offers from both!

Another book in the same line is E. Joseph Billo's "Excel for Scientists and Engineers," Wiley-Interscience, 2007 ISBN 978-0-471-38734-3, including CD.

You may or may not agree with using Excel, but if you do, this book will help with roots of real and imaginary equations, ordinary and partial differential equations, matrices, and statistics.

Sometimes you just don't have the luxury of using Matlab, Spotfire, etc.
