I got several students who need improve their English in short time. They have very similar situation. All if them don't need use English before. But they suddenly got new situation, they may got a new job, they need have very good English level to pass their probation. But they don't know how. So they look for a teacher for help. A good teacher is very useful to help them successful. MyTuitionGuru helped them and they were very grateful.
But we felt very pity for this. If they really spent some time learning English, they don't need worry too much for their probation. It is so easy to master English as an adult by learning English in about 10 minutes a day. Just wonder how much you can learn in one year, two years and years.
