Another question.
Did you know that the aggregate actually comes with 4 decimal points but they are not made known to the public?
Mary and Jane could have gotten 239.0031 and 239.0008 respectively. Although the school cut off score to the public is 239, the actual cut off score could be 239.0025. In this case, only Mary got in.
