Send me the exam blueprint and I will map your material against it, free.
The audit is free, with turnaround in days. You get a per-domain coverage map of your existing material against the published blueprint, the question counts it would take to close each gap, and your build figure in writing, quoted as a range with a not-to-exceed, so you can take a real number to whoever approves the spend. It is yours whether or not we ever work together. I take two a month.
