Why at, in and on are hard to sort out

Most learners of English can name the three prepositions of time and place, yet still hesitate when a sentence asks for one. A quiz is a good way to test that, and grammar quiz on at, in and on practice works best when the questions come from the rules your class is actually using. If you are looking for a ready-made printable worksheet, this page will not give you one. DeckOwl builds a quiz from your own material, so the examples match your course.

Multiple-choice, true/false, and short answer questions, each with an explanation.
Questions generated from your own PDF, DOCX, PPTX, notes, or page photos.
Free plan: 3 generations per month, studied in the browser.
Plus adds PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML export.
