DELF Grammar

You want to prepare for the DELF exam, and you realize that you’re going to have to improve your command of French grammar. Quite a few teachers nowadays seem to shun grammar in favor of communication and fluency, but the exam is going to require good grammatical knowledge of French. The problem is you probably aren’t too sure what grammar topics to study. Sure, you open your old French textbook, but that may be of limited use. Should you focus on things such as “par, pour, en, vers, avec, de, sans, sous, sur” or perhaps you would be better of focusing on verb tenses.
