Know your score before test day.

Onterra Tutor is daily practice for the four big English exams: IELTS, TOEFL iBT, PTE Academic and the Duolingo English Test. Answer real task formats, get an examiner-style score in about a minute, and see exactly what to fix before you book.

WRITING
Score your essays against the official band descriptors for your exam. Every verdict names your three costliest fixes and shows an upgraded paragraph as a readable diff, so you can see precisely what a higher band looks like in your own writing. IELTS Task 1 and Task 2, TOEFL Write an Email and Academic Discussion, PTE essays in the official 200-300 word form, and Duolingo writing tasks.

SPEAKING
Record your answer on your phone, read the transcript, and get scored feedback on fluency, vocabulary and grammar. Then listen to a model spoken answer for the same question.

READING AND LISTENING
Original practice sets in the official format for every exam, marked the moment you submit. Save a set for offline and practise with no connection: your attempt is queued and scored when you are back online.

ONE ASSIGNMENT A DAY
Open Today and your practice is already chosen: one writing task and one set, in your exam. No deciding, no menus. Keep your streak alive, and the app forgives one missed day a month.

TRACK YOUR PROGRESS
Your predicted score updates as you practise, with a chart of where you started and where you are now, per section, on your exam's own scale.

BUILT FOR TEST TAKERS EVERYWHERE
Pick your exam once and everything follows: questions, scoring scale, targets and model answers. TOEFL scoring follows the current 1 to 6 half band scale. PTE uses 10 to 90. Duolingo uses 10 to 160.
