The English Stumbling Block by leah angstman/Various Authors ($2)

This is exactly as it appears: a grammar test. It's not fun, and it's not easy. If you feel like challenging yourself (or your students!) to a hard test on the stubborn (and sometimes ridiculous) rules of the English language, then this test is for you. Pronoun agreement, parallel structure, commas, run-on sentences, split infinitives: it's all here. The test includes the option to mail it back for full correction by a Propaganda Press staff member.
