Please email me and let me know who you are and in what capacity you are using the site. It's fun for me to know who is using the site and useful to you if there are changes to the site or information I need to get to you.

If you find mistakes, PLEASE! let me know. I rarely find time for proof-reading and I know there are mistakes on the site.

Not all of my materials are on this site. I have new worksheets available for both IPC and Physics. More information here.
