Proofreading makes you accurate
Spotting someone else's mistake is easier than avoiding your own, and it builds the same awareness. These sentences use classic errors such as "She don't", "interested on" and "look forward to see", so you train your eye on the slips that appear in real emails and essays.
One rule at a time
After each answer you get the corrected sentence and a short rule. That tiny explanation, right after you made a decision, is far more memorable than a page of grammar notes.
Find the Mistake: questions and answers
Is there always exactly one mistake?
Yes. Each sentence has one wrong word, and changing that word makes the sentence correct.
Which grammar topics are covered?
Subject–verb agreement, tenses, prepositions, irregular verbs, gerunds, comparatives, conditionals, inversion and more.
Do I lose points for a wrong tap?
A wrong tap ends that sentence and shows the answer, so read carefully before you tap.
