Teachers have access to modern EdTech tools to enable the 21st-century learning environment. • Student interaction We want the classroom to be interactive, and we make sure of it with our AI assistant who accompanies the two teachers in each session. The system monitors every student’s emotion and attention, and the teacher adapts their teaching style to the students' needs. Our advanced AI can formulate a learning curve, and prepare a lesson plan with an assignment and teaching aid, personalized to each student. We achieve this by studying the students learning patterns over time (‘machine learning’). This ensures a holistic teaching-learning process, matching the requirement of each student. • Assessment and test We conduct summative and formative assessments and tests online. Our teacher and AI assistant prepare the assessment and tests and also correct all the answer scripts.

It can guide students on the path of their unique identity and career/passion. We aim to help students excel in what they are best at.
