Learning a foreign language - Check.
Taking a GCSE in that Lanuage - Check.

If I was to teach english to speakers of another language-- Would I need any other GCSE's other than my language one & my Tesol qualified certificate??

I'm in a pickle, I've left it too late to do my GCSE's in school, so I'm wondering whether to waste 2 years at college to get Gcse's that I may not even need in the first place.

If anyone could help it'd be great. Thanks
