I applied for a new idea. Personally, I think it's better to study hard by myself, whether it's choosing new ideas or other training institutions, because they are all commercial, profit-oriented and play an auxiliary role. And the tuition fees for new ideas are uneven. The difference between the money I paid then and the money I signed up for now is nearly 2000. If there is no problem with the funds, this is not the point. If you are a teacher, because everyone has different levels, you can only say that there are good and bad.
