Dao’s Trail · 20 story sets · 30 items each · Sets 1–2 free · Sets 3–20: US$3 once
Each set is one episode of a continuing story about Dao, who returns to her home province of Nan after university and trains to become a mountain guide. You meet English tenses in real situations, then see why each answer is right and how each wrong tense should be corrected. Start with the two free sets. If the practice helps you, one small payment opens the other eighteen.
