I’ve just been told to tell you, C1 students, that penalisation for wrong answers in the reading and listening test is not sure but just an option.
On the other hand, let me remind you that the test may have a “use of English” part. This may or may not be included in the reading part. “use of English” is basically any kind of exercise aimed at testing the candidate’s knowledge of grammar or vocabulary, such as a text with gaps to fill in. Yet again, this is just an option. I know nothing beyond this.
Sorry once again about this whole mess.
