If there’s one thing that a lot of students in both secondary and high school nowadays that they are asking is how long will it takes to get to 6.5.
There is a general answer to this question. First of all, the level of the student must be assessed in order to ascertain the current level. Aside from that, the assessment will reveal the weak areas and strengths of the student. These weaknesses have different duration until they are enhanced. For example, if the weak point is word stress or pronunciation, this will take a bit longer than listening and reading. In terms of writing, it will also take time if the weak points are grammatically based whereas if it is content based, the student or candidate is easier to be trained. Lastly, it will also depend on how busy the student is outside his or her IELTS class. If IELTS is the only or just few of the focuses, then it is faster since the attention and mental capacity of the student is solely focused in preparing for the test.
The assumptions that the student is at least at his or her pre-intermediate level (4.0-5.0 IELTS equivalent) and in a one-on-one class or a small group class. However, if the student is in a group class, the number of hours can be doubled since the IELTS teacher needs to mind many students in a class.
To conclude, in general, for 1 or 2 students in a class, it takes at least 150 hours in-class lectures, training, and exercises plus at least 150 hours out-of-class review and exercises. On the other hand, if it is a group class, the number of hours can be doubled.
