Need more interaction between the teacher and the students in order to improve students English skill rather than just depending on the system only. Social class and activities too much students and they love to talk stupid and nonsense thing during the lesson, and many times they didnt want to talk or discuss during the breakout room, yeah wasting time. For WSE Go im sorry i dont really satisfied with the service and for me myself the price is not cheap. Maybe for offline class should be better, but its impossible now during the pandemic, because what I felt for the WSE go online class is just the same with a free application that I can download on my phone. So what I felt here is more depending into self learning with the system rather than studying with the teacher.
