I am a native speaker of English and I just got my provisional online IELTS results. My LRWS scores were 8, 8.5, 9, 9. Overall, 8.5. On listening, one section I accidentally reversed my answers which led to the 8 in listening. This means I have CLB 10 in everything but listening, which is CLB 9. Is there any point difference between 9 and 10?
