Welcome to my Library of Skills Materials!

Below are intellectual properties of some of the skills I teach.  They are free to you, and you may share them freely, provided you give proper attribution to me and do not charge others.

If you see a skill of interest, I invite you to first download and attempt the Diagnostic.

Then, you may refer to the Diagnostic Solutions to see whether you are ready to learn that skill.

If so, you may use my Self-Study Workbook to help you learn and keep you accountable.

If you are having difficulty, hire me to teach you (see Engagement details here).

Business Calculus

Linear Programming
