Hello, two repeated courses are not bad. For example, Haowen's re-reading course adopts a small class system of about 25 people. According to the different levels of students, different teaching methods and teaching progress are adopted to narrow the scope of teachers' attention after class, so that teachers can have the energy to pay attention to each student's knowledge mastery and realize teaching in accordance with their aptitude, which is helpful to establish self-confidence and improve students' learning concentration.
