===== C1 Grammar Focus =====
**What it is:** Advanced grammar choices for style, emphasis, and precision.  
**What it’s for:** Sound natural, formal when needed, and express subtle meaning.  
**Example:** “Had I known earlier, I would have acted differently.”

===== Focus areas =====
  * Advanced conditionals & inversions (Had I…, Were I…)
  * Mixed conditionals (past condition → present result)
  * Modals for speculation (may/might/could have)
  * Complex relative clauses and reduced clauses
