Some experimental notes

For candidates for the Linux Professional Institute LPIC-1 exams and the Canonical Ubuntu UCP exam there's a promotion available that will let you buy all three test vouchers together at 20% the usual rate.

LPIC is the respected vendor-neutral Linux professional certifcation, and Canonical's updated UCP program requires the LPIC-1 certification (two tests) as a prerequisite.
