On 18th September 2025, the third class of the Sundarban Faculty Training was held at Cheenta Academy’s Kolkata office. Only Rupa and Chandra attended, with Chandra showing consistent participation. The session introduced Canva for creating business posters, developed a roadmap for Sundarban Tourism, and planned local surveys along with learning the basic geography of the region.
On 11th September 2025, the second class of the Sundarban Faculty Training was held at Cheenta Academy’s Kolkata office. Two new teachers, Rupa and Brihospoti, joined the programme, while Sudipti and Suveccha were absent. The session introduced Google Docs for lesson planning and included discussions on leadership and business development, with ideas for small enterprises in the Sundarban region.
On 28th August 2025, four teachers from the Sundarban region began their training at Cheenta Academy’s Kolkata office. The first day focused on self-introductions, classroom practices, integrated learning, and computer basics, marking an important step towards teacher empowerment.
Cheenta Academy proudly celebrates the success of 27 current and former students who qualified for the Indian Olympiad Qualifier in Mathematics (IOQM) 2025, advancing to the next stage — RMO. This accomplishment highlights their perseverance and Cheenta’s ongoing mission to nurture mathematical excellence and research-oriented learning.
August marks the pivotal month when the Cat-Scan app takes its final shape. The focus shifts from coding individual features to integrating the app, preparing for user testing, and fine-tuning the database and user interface. By the end of this month, the core functionalities—image capture, pupil detection, and AI predictions—are up and running, ready for […]
Students begin coding the Cat-Scan app, integrating Python’s OpenCV for pupil detection and TensorFlow for AI predictions. The app’s simple UI guides users through cataract screening with real-time results and visit tracking.
June opens with a practical goal: turn May’s plan into a working, pupil-first pipeline. The first week focuses on data hygiene. A simple utility groups images into clean folders, fixes broken names, and flags duplicates. Students can now find, compare, and reuse images without guesswork. Attention shifts to what a field worker will actually see. […]
The month begins with a new cohort of students joining the program and meeting a clear reality: in many villages, a cataract check can cost an entire day’s travel and lost wages. The team frames the business problem in plain terms—early screening must happen close to home, be simple to use, and lead to timely […]
In August, Filibot shifted gears from building to refining. With real games tested and the website live, students focused on improving usability, documenting processes, and exploring educational data. A new phase of reflection and innovation began—with teamwork, feedback, and a bold vision for what comes next.
In July, Filibot entered the digital phase. Students began coding the Filix School website, developing smart grading systems and AI-driven report cards—transforming educational ideas into functional tools through HTML, CSS, JavaScript, and teamwork.
