PTE practice tests with instant AI scoring and realistic mock exams
Every speaking, writing, reading and listening response is graded immediately with feedback that tracks the PTE scoring criteria, so you can iterate on the same task within minutes.
Sit complete tests under exam timing, or target one skill or task type with sectional mocks - including the unusual 'create your own mock test' builder.
Thousands of questions modelled on real PTE Academic, UKVI and PTE Core formats, kept updated to match current exam patterns.
Dashboards track scores across attempts and break performance down by task type, highlighting exactly where your score is being lost.

Agentic QA that tests every change like a real user and opens the fix PR
Pie maps your real user flows from a URL or build and finds elements by looking at the screen, so there are no selectors to maintain.
Each PR is read and exercised against the running app, so regressions are caught before they reach users.
Tests survive redesigns and deep links because they rely on how the interface looks and behaves, not on brittle CSS or accessibility paths.
When Pie confirms a bug, it drafts a fix PR with the root cause and the applied change, ready for review and merge.
