FAQ ## Questions, answered Everything worth knowing before you sit your first mock. ### Which exams does topin cover? GRE General, TOEFL iBT, IELTS Academic, GMAT Focus Edition and the digital SAT. Each has its own interactive lessons, section-wise practice, mock tests and tracker. ### What are interactive lessons? Short, hands-on lessons where you learn by doing: drag, tap and solve as you go, with instant feedback on every step. Each one covers a topic that shows up on your exam, and the tracker points you to the lessons behind the questions you get wrong. ### Are the mock tests timed like the real exam? Yes. Mocks are full-length and timed, and they follow the real exam's section order and structure, so test day feels familiar. ### What does the question tracker actually track? Every question you attempt: whether you got it right, how long you took, what you picked, and which section and topic it belongs to. That's what powers your weak-spot list. ### Can I practise just one section? Yes. You can drill a single section or a single topic, like GRE Data Interpretation or IELTS Listening, without sitting a full mock. ### How much does topin cost? A one-time pass per exam, from $19, with no auto-renew. Each pass opens all 8 full-length mocks marked on the official scale, the full practice bank with explanations and every lesson for that exam. Creating an account costs nothing, and prices are shown in your local currency where we can.
