Strong command

0 – 6: Foundations to strengthen | 7 – 12: Developing command | 13 – 16: Strong command

A score of 7 indicates developing command, meaning you can spot many common complements but may still mix up types such as direct vs. indirect objects or complement clauses in trickier sentences.
