This is a classic Obiettivo Grammatica exercise.
Obiettivo Grammatica is not flashy. It won’t make you fall in love with Italian through songs or memes. But it will make you understand why you say “sono andato” and not “ho andato.” The PDF version is a solid, affordable choice—just make sure you buy it legally and supplement with listening/speaking practice elsewhere.
However, the goal of studying grammar should not be "perfection" for its own sake, but rather "flexibility." True linguistic mastery allows a writer to know the rules well enough to know when to break them for stylistic effect. A poet might shatter syntax to evoke emotion, but they can only do so effectively because they understand the structure they are subverting.
