Individual learning program: Every day, the student receives 15-20 tasks. By solving them, the simulator identifies gaps in knowledge and shapes the training for the student. We explain through lectures and examples: The student is not left alone with the task - the simulator has an explanation for each task. We monitor progress, provide reports: The student's solutions are available in the application - what has already been mastered, where difficulties arose, and how his level is changing. We stay in touch: If something is unclear, you can always ask a question. The support team answers parents and students in the "Qalan Chat" section.
