This is a review sheet to remind students of all of the different types of irregular forms that exist in the preterit tense (VERY irregular, CAR/GAR/ZAR, stem-changing, irregular stems, etc). It is specifically designed for students in Unidad 4 of the Avancemos 2 textbook, but it could easily work well for students of any text or level. (Just delete the page numbers listed for reference.) There is also a short section to review the imperfect forms. The third page consists of questions using the different verbs with irregular stems in the preterit.
