What does number 666 mean?

It's my second year at community college and im finally a full-time student taking the maximum unit of 19 units is the highest you can go unless you get permission from a counselor. When i paid my schedule and bill it came to a total of $666.00. i know its my first time taking many cles this fall semester but does the 666 mean anything bad? ill be honest im a hard working student i give it my all thats why im ding full to transfer to a csu. does the 666 mean anything bad? or do i have nothing to worry about. cause i know taking 6 cles is going to be hell, and im unemployed right now and im turning 19 yrs in a month.
