The Answer Key alone won't make you fluent. Combine it with these tools for best results:
Keep a notebook where you transfer incorrect answers from the key. Categorize them by lesson and grammar point. Review this log weekly.
When you check your answer against the key, you aren't just seeing "right or wrong." You can analyze why your sentence was different. For example, did you use the wrong conditional? Comparing your attempt to the model answer clarifies subtle grammar distinctions.
Contains answers to the grammar transformation and sentence substitution exercises.
