I teach an Internet class with Yahoo email registration. Often it will not accept a correct zip code. Why?

should I apply for online classes when they want you to use internet explorer for the registration,and you?

aren’t able to run internet explorer,but when you say to them that you have Firefox,they say that you won’t be able to register,because you won’t be able to finish the registration,Sorry about the long-winded question,Any Suggestions,Ideas?

ACT registration question. Is Computer Programming/ Internet Lit a Computer Science class?

I need to know for filling out my ACT registration, it is due tomorrow. The class taught in depth programming in Visual Basic and did an in depth unit on HTML.
Also, is Personal Finance considered an Economics or Consumer Economics class?
