hello good day. I'm thinking of applying for the CELTA COURSE, I'm a high school graduate and I'm a housewife looking forward to apply for the CELTA COURSE, I'm very good with English and I have passion for teaching this language in schools and/or institutes.

Is it a hard course? Should I have a diploma or any sort of a university degree to apply? What are the requirements? And is it eligible worldwide? Can I start working when I'm done or I need to gain another university degree?
What levels can I start teaching when I get my certificate? And should I apply for the DELTA after the CELTA?

Thank you in advance.
Hadeel
