120 Rules of Grammar is an exam-oriented English grammar book by Nimisha Bansal, primarily designed for candidates preparing for banking, SSC and other competitive examinations.

The book's central approach is to teach important grammar rules and then apply those rules through error-detection questions, practice sets, strategies and mock tests.

Rather than functioning like a traditional school grammar textbook, it focuses heavily on the types of grammar errors and sentence-based questions that appear in competitive examinations.
