We guarantee that students who attend 60+ hrs of IELTS reservations made with our IELTS specialists (https://www.cambly.com/en/student/pro) will increase their IELTS speaking score by at least 1.0 points. We measure the increase based on an official pre-test and an official post-test. Students whose scores increase by less than 1.0 points are entitled for an additional month of Cambly's 60 min, everyday subscription at no cost (a $180 value).


The pre-test must be an official IELTS exam dated before the date the student begin using working with Cambly's IELTS specialists. The post-test must be an official IELTS exam dated after the date the student completed 60 hours of IELTS reservations with our specialists to up to 6 months after the date the student completed 60 hours. The student is responsible for submitting a scanned copy of both official pre-test and official post-test to Cambly at [email protected] in order to claim the free subscription. Once the free month is claimed, it must be fully used within 12 months of the claim grant date and is non-transferable.
