Background: Resolving G-Kentei Learning's 'Four Major Stumbling Blocks' with a Smartphone App

The G-Kentei (Generalist Certification / organized by the Japan Deep Learning Association) has seen a rapid increase in examinees in recent years as a qualification that certifies AI literacy. According to JDLA's announcement, as of the end of the G-Kentei held in January 2026, the cumulative number of examinees reached 202,215, and the cumulative number of successful candidates reached 142,042.

However, examinees also face challenges such as 'not knowing where to start learning' and 'difficulty in continuing review'.

❌ Don't know where to start studying ❌ Difficult to review even after solving problems ❌ Hard to create a review flow with textbooks alone ❌ Difficulty in continuing learning

Wazaaca upholds the philosophy of 'from vertical education to horizontal co-education' and is developing a learning OS that converts knowledge into reproducible 'skills'. This iPhone/Android version was designed to enable efficient progress from foundational learning to practice and review for G-Kentei success, all on a smartphone.
