1.How is my performance assessed?
Examiners will evaluate your performance according to 4 criteria namely fluency and coherence (FC), lexical resource (LR), grammatical range and accuracy (GRA) and pronunciation (P).
2.What is the most important criterion in the speaking test? Is it grammar?
No. The 4 criteria are weighted equally at 25% each. The examiners will give a result for each criterion and then work out the average of the 4 scores which equates to an overall speaking score. If you get 6 for FC, 5 for LR, 5 for GRA and 6 for P, then you will receive 5.5 overall for speaking,
3.Will I lose points if the examiner disagrees with my opinion?
No. You are judged on your English, not your opinions. There is no right or wrong opinion.
4.How is my performance assessed?
Yes. As long as you keep talking and use a wide range of English, you can get a high score as this is not an IQ test. Boring or obvious opinions are fine if you can produce a wide and accurate range of language when expressing them.
