From C1 to C2
Cambridge English estimates around 1,000 to 1,200 hours of guided study in total to reach C2. The step is about subtlety: idioms, style, register and humour, and understanding virtually everything you hear or read with ease.
- 1
Read widely across styles: literature, opinion columns, academic writing
- 2
Notice how native speakers soften, emphasise and joke, and borrow their phrasing
- 3
Write regularly and get feedback on style, not just on mistakes
