- Correct! he would be back at work in six weeks can be replaced by this, and is a noun phrase. It functions as a direct object.
- Incorrect. Subject/Verb/Object: Morgan/thought/.... The object is a noun phrase, but it follows the same word order (S/V/Oplace|Otime): he/would be/in the swimming pool/at six o'clock. (Morgan thought he would be in the swimming pool at six o'clock)
- Correct! Normal word order: Subject/Verb/Object: The taxi driver/reckoned/.... What did he reckon? That the journey would take 30 minutes. This is a noun phrase, and it takes normal word order.
- Incorrect - You probably spotted that one! What should it be? Use normal word order to make an independent clause, with Subject/Verb/Object: Louis/thought/(that/he/would be staying/in a nice hotel).
Complex sentence
If your writing is technically correct but reads like a list of short, disconnected statements — I overslept. I missed the bus. I was late. — you've hit the limit of what simple sentences can do. Complex sentences are how you fuse those into one flowing thought (Because I overslept, I missed the bus and was late). It's the single biggest jump in writing maturity.
A complex sentence combines an independent clause with at least one dependent clause: I missed the bus because I overslept. The dependent clause typically signals time, reason, condition, or describes a noun, and is introduced by subordinating conjunctions (because, although, if, when) or relative pronouns.
C1 | Advanced
If you've ever sat through a lecture in English, written a complaint letter, or argued a point in a meeting and come out feeling actually understood — not just tolerated — you've felt what C1 looks like. The level matters because it's where most universities, certifications, and skilled-work environments draw their language line.
C1 is the advanced level in the CEFR framework, demanding fluent and flexible language: inversion for emphasis, mixed and advanced conditionals, formal subjunctive, cleft sentences, and complex nominal phrases — all used appropriately across registers.
Difficulty: Medium
If easy questions feel too obvious but hard questions leave you guessing, you're probably ready for Medium — the level where most real learning happens. It pushes just enough to expose the rules you don't quite have yet, without burying you in edge cases. This is where steady fluency is built, one well-aimed challenge at a time.
The Medium difficulty tag marks middle-range challenges — typically A2 to B1. One rule per question, realistic distractors, and contexts that require active thought rather than instant recognition.
