For various reasons the number of applicants has increased. This means that the proportion of candidates achieving 112 or more will also increase although the numbers required have not.
While 120 might be sufficient for one candidate it does not follow that it will be sufficient for another. Compare, for instance, a graduate with a 1st class honours with a direct entrant applicant with 2 A-level. Even there the issue is not clear cut as the nerd or geek factor will also be considered.
What is pretty certain however, and everything else being equal, the higher the score the lower the training risk.
