Limited bandwidth is a common challenge faced by most schools, especially at the primary level where internet connectivity is usually restricted or limited for a variety of reasons. The Vretta App is custom-built to support DTab, designed as a large scale interactive assessment platform that functions in an offline environment. A custom data structure allows for the offline collection of data. After completing the assessment, wi-fi is enabled to synchronize the data from the tablet to the online data structure that is accessible to administrators for the purpose of evaluation.
We follow the highest quality standards to design and develop our tests and learning materials. Our reputation rests on our steadfast pursuit of delivering outstanding learning and testing experiences to students.
