What you will get

The rule in two simple sentences, five examples, the mistakes learners from your first language usually make, a quick comparison table and a ten-question exercise with answers.

Why it works

Grammar rules make sense faster when they are compared with your own language, so the prompt asks for the mistakes typical for speakers of it. A short rule, examples, a table and practice follow the order people learn in: understand, see, compare, use. Writing your own sentences, as the tip says, is where the rule becomes yours.

Common mistake

The explanation uses grammar terms you do not know.

Fix: Give your level and ask for no technical words, or for each term to be explained in brackets the first time.

Also watch for

The common mistakes are not the ones you make. Add two sentences you wrote with the error. The AI can then explain your real pattern.
You read the answers before trying. Ask for the exercise first and the answers only after you reply.

Try a variation: speaking practice

Ask for five short questions you must answer out loud using the rule, with model answers to compare after.
