nervous about my English and future Hello! I'm studing to become an interpreter and translater (English-Spanish). I'm really scared because this year I will finally end my career. But I have a huge problem! My English is not the best and I don't know what to do. I mean if I have to work I will be really scared because I really think my English is just ok I mean it is not good enough how it should be. I get really nervous when I have to speak in English in front of people and I start to stammer. And besides my English mm grammar is not the best. Preposition are my nightmare haha. and I don't know if someone wants to help me with my English I would really appreciate it. =)
