Nothing on this test is intended to be tricky.
Please show a little work on each problem where possible.
DO NOT USE A CALCULATOR. I need to understand what you know when you are working without any type of math help.
Send your answers/work by email, please.
I will reply within one day. Please let me know with a polite note if I do not.
Complete test within 1 hour. Tell me the time that you took.
