It should still be easy to do, and students of all English levels and stages have it. The pressure is naturally great. Most of them study in their spare time and have a strong desire to learn, so they have higher requirements for teachers. Therefore, teachers in this field must be super patient and have teaching ability, and can't just talk about grammar at school. Generally, very formal training institutions need to train lecturers before they can take up their posts.

All the above are related to the teacher's personal quality. The rest depends on the operation mode of the school or training institution itself. Most schools are still good, and some training institutions generally just recruit students and leave them alone, putting a lot of pressure on teachers. Including frequent class schedules and so on.

If you love the profession of teachers, and the training institutions themselves are professional enough, there should be no problem.
