Please be advised that your Overall IELTS Band Score and Writing Overall Band Score are calculated and rounded in slightly different ways.
Overall Band Scores are reported to the nearest whole or half band. For the avoidance of doubt, the following rounding convention applies; if the average across the four skills ends in .25, it is rounded up to the next half band, and if it ends in .75, it is rounded up to the next whole band.
L: 6.5, R: 6.5, W: 5.0 and S: 7.0 – Overall Band Score of 6.5 (25/4 = 6.25 = Band 6.5)
L: 4.0, R: 3.5, W: 4.0 and S: 4.0 – Overall Band Score of 4.0 (15.5/4 = 3.875 = Band 4.0)
L: 6.5, R: 6.5, W: 5.5 and S: 6.0 – Overall Band Score of 6.5 (24.5/4 = 6.125 = Band 6.0)
Writing Overall Band Score is made up of your performance on two separate writing tasks, more commonly known as Task 1 and Task 2. But what you may not know is how these tasks are weighted against each other to formulate your overall writing band score.
