Marathon for English School

A marathon was designed for the English language school.
The bot automatically sends the material for learning and accepts the task performed. The gate is built out of 10 tasks, and at the end of the marathon participants receive different bonuses. As a result of the performance by the participant of the task, the teacher comes a notification and in a limited time he needs to check the DZ and give feedback with the assessment, and at the same time the participant receives a new task and delays on the performance of the new DZ. Whoever doesn’t put into the deedline, goes out of the marathon.
