I'm often asked about the mechanics of the CAE exam. Students know they need 60% to pass the exam, but aren't sure exactly what that means.
"I'm terrible at listening. Do I need 60% in listening?"
The answer is no, you don't. You need a 60% average across the sections. So if you get 50% in listening, you could still pass by getting 70% in reading, speaking, use of English, and writing.
If you have an engineer's mind, you'll realise there's a lot of scope for optimisation. If you think your writing skills are pretty good, it might be better to invest the last few weeks before your exam brushing up your listening skills. If you lose a lot of points in the Use of English sections, dust off your old grammar books!
