CLB 10 Email Writing
At CLB 10, your email reads like it was written by a native English-speaking professional. The evaluator shouldn't be able to tell it's a test response — it should feel like a real email.
The difference between CLB 9 and 10: naturalness. CLB 9 emails are impressive but can feel "academic." CLB 10 emails feel effortlessly professional.
Register Control
CLB 10 writers effortlessly switch between registers:
Formal (complaint to a company): "I am compelled to bring to your attention a matter of considerable concern regarding the service I received on March 15th."
Semi-formal (to a colleague): "I wanted to touch base about the presentation next Thursday. I've noticed a few areas where we might want to make some adjustments."
Warm formal (thanking a teacher): "I cannot overstate how much your guidance and encouragement have meant to me throughout this program. Your dedication to your students' success is truly remarkable."
The skill: Reading the scenario and instantly calibrating your tone. A complaint to a hotel manager differs from a suggestion to a friend differs from a thank-you to a mentor. CLB 10 writers nail the register on the first sentence.
Sophisticated Vocabulary Integration
CLB 10 vocabulary feels natural, not forced:
Forced (CLB 8): "The event was extremely unsatisfactory and I am very displeased." Natural (CLB 10): "The event fell considerably short of the standards one would expect, leaving many attendees disappointed."
Key phrases that sound native: - "I trust that this matter will be resolved at the earliest convenience" - "I would welcome the opportunity to discuss this further" - "It has come to my attention that..." - "I feel compelled to address..." - "This warrants immediate attention" - "I am confident that a mutually agreeable solution can be reached"
These phrases aren't fancy — they're what native English-speaking professionals actually write in real emails.
The Zero-Error Standard
At CLB 10, the standard is zero errors. Your review process:
1. First pass (content): Did I address every bullet point thoroughly? 2. Second pass (grammar): Read each sentence individually. Check subject-verb agreement, tense, articles. 3. Third pass (flow): Read the entire email aloud in your head. Does it flow naturally from opening to closing? 4. Final check: Is the tone appropriate? Is the word count in the 180–220 range?
Time budget: 18 minutes writing + 9 minutes reviewing. Yes, spending 9 minutes reviewing is correct at CLB 10. Error prevention is the priority.
