Testcentre’s landing page: “Rəsmi formatda sınaq.” — a mock exam in the official format — beside a live SAT question and a score forecast.

How it was built

An academic exam platform covering SAT, IELTS, TOEFL, GMAT, GRE and the national university entrance exam. It opens with a diagnostic across eleven dimensions, then builds a thirty-minute daily plan that reshapes itself as scores move. Full-length simulations run in real exam format, and every question carries a video explanation.
