Abhilash AI Research Lab — English Grammar & Usage (english)
A synthetic dataset of ~5,000 grammar, vocabulary, and usage exercises, from the Abhilash AI Research Lab.
How it was made
Every example is produced by generators written for this project — hand-authored templates, rule tables, and solvers. Answers are computed in code (math and reasoning) or derived from authored rule tables (English), so each answer is verifiable and the whole set is reproducible from a fixed random seed.
No third-party language model was used to generate the content. This is a synthetic educational dataset for research and experimentation. It is not a benchmark and not human-expert-curated. Some phrasing is templated.
