The variations in the IELTS score of four students in two subsequent attempts are shown in the given tables.

It is evident from the tables that all four students made their scores better in the second attempt. Among them, John exhibited a consistent and more progressive change in his band score. His score was the least(4.5) among the group for all four modules, which he made better by adding two to all.

The highest individual band score achieved was by Jessica in listening(8) in the first attempt,which she could not maintain in the second. However, she made the rest of her scores better. The overall score disparity between Peter and Mathew increased from 0.5 in the first to 2 in the second attempt, of which the latter’s score was on the higher side. By contrast, the margin of success was higher for the former.

Overall, when Mathew remained the most successful test taker in both attempts, John managed to get the best margin of success.
