@tommy_00 There is no official group by either ETS (TOEFL) or BritishCouncil (IELTS). However, there are groups created by different tutorial centers that help test takers in jurisdiction prepare for test.
If you are their student and registered for the test you will directly linked to the organizers. If not, you can google IELTS Group Links 2021, then choose telegram, whatsapp, facebook, or other apps. Start from there. Good luck!
@Mina-Creative I can understand what happens with you. I learned Turkish completely by myself with the help of few friends, at first It was hard to speak but by practice I got good at it and same goes for English or any other. I suggest you to watch English movies or videos more and improve your listening skills and try to follow along the video or even sing song. That'll help you to build the confidence to try to speak. Happy learing and you can ask me if you need any other help 👍
