@Thesexier: IELTS and TOEFL are commonly deployed tests of English for academic purposes.
Your original post seemed to indicate that you were concerned about your English skills in the context of the pre-IB program you are about to join.
My post was telling you that in my (professional) opinion, your language skills seem good enough (I’ve read other posts by you on this forum) – if your English literacy is generally as good as it is on Fluther, you really needn’t worry too much about your language skills. Remember, it’s a teacher’s job to make sure you understand, so if you don’t or you’re having trouble following, ask your teacher.
The pre-IB programs are there to prepare you for the IB programs – you’ll have the opportunity to practise the skills you need. Presentation practice is a part of this.
