Reddit reviews The Ultimate Italian Review and Practice (UItimate Review & Reference Series)

This book is the best textbook I’ve seen. The verbs can be complex but as a French speaker you have an advantage over people who only speak a language like English because you’re familiar with a language that prominently features things like conjugations and subjunctive tenses.

Truth be told, the only way to have a marked improvement in a language is to use it use it use it. If you have a friend who speaks Italian, try to practice with them. If you don’t, for practice speaking, try reading a book that’s been translated into Italian out loud. Don’t even necessarily worry about understanding what everything means; you’ll start to pick up on things that are commonly used and you’ll notice your studying becomes much more targeted and productive, plus you get to practice the act of speaking, your accent, and all that good stuff. For comprehension, watch movies in Italian, and put the subtitles in Italian. That’ll help give you a reference for how people talk and it’s the best way I’ve ever found to improve comprehension aside from one on one conversation with an Italian speaker.

I've been using The Ultimate Italian Review and Practice. It has a pretty good explanation of grammar and plenty of exercises in each section. All of the answers to the practice exercises are in the back of the book. In bocca al lupo!
