One bit of advice that i would give for those who are worried about not having experience is to basically do volunteering work...the great this is it doesnt even have to be teaching etc...

For example if you are wanting to teach in schools in another country then volunteer at an out of school club or a youth group...its great for the CV and to talk about in the job interview because it shows you have had experience working with kids...albeit not in a class room environment but you will develop similar skills to those needed in a classroom such as, how to control children, dealing with children who are naughty or loud etc, organising activities etc...some youth groups are once a week and last about 2hours and occassionally trips are planned and you get to go for free...so if you have the time then you can do it whilst doing the TEFL course - i know i did
