I don't know what btec course to take up in college?

My connexion advisor suggested to choose a btec course due to my not so good gcse's result though I still dont know what to take up. I want to be an English foreign language teacher in the future. But by looking at these prospectus of courses he gave me, I'm not sure.. I've filled in the apps just the section relatated to choosing a course that needs filling & ref :\ help!!
