A 125 is a high, competitive score and requires advanced English ability across reading, listening, speaking and writing. It’s achievable but demands targeted practice: learn the test format, build vocabulary and grammar accuracy, practise timed speaking and writing tasks, and take realistic mock tests to improve fluency and coherence. Many test-takers reach 125 with structured study and focused feedback on weak areas.

Vouchers purchased from us are valid for 10 months from the date of issue. Each voucher provides one Duolingo test credit; make sure to redeem and schedule your test within that 10-month period.
