Learning English is like taking antibiotics … If your teacher has deep knowledge and broad experience, has proved results in various situations, international experience … and follows a serious pedagogical program, TRUST him or her. You will learn some things immediately and others later, but be focused, read a lot (reading helps you in grammar, listening and vocabulary) and remember … antibiotics need to be taken till the end of a cycle…
In other words … give some time so the result of your teacher´s work appears.
