Scrumpy, don't place too much credence on the score. The aptitude score is only on tick in the box.
Like your 5 GCSE A-C where there is no distinction between 5 A* and 5 C or between A-levels in underwater basket weaving or rocket science. They are all ticks in boxes.
It is your performance in the leadership exercise and at interview that are the crunchers.
I am not really comfortable swapping scores as you would be doubly gutted if someone else said they got in with 118. What you don't see is the PQ scores etc.
