Oxinity's online English classes by videoconference seek to consolidate the content that we have identified as not known by the students. The teacher saves in each activity if the students have acquired and exceeded the objective. Then, through the Oxinity app and its game, we make sure that what we have seen in class has been assimilated. The first questions in the game are always about what was studied in the previous class. Once these questions have been passed, the next ones are about the next class, and in this way progress is made until completing the 150 linguistic points, structures, comprehension, and the more than 3,000 words that we intend to complete in less than 3 years.
