As a PPL student, I was curious to find out what a Tower or Radar controller would do/say differently if I introduced myself on the frequency as 'student G-ABCD'.
As a radar controller (well any controller I guess!) it highlights straight away that you are a PPL student with low hours and therefore may need a little extra care and attention. For example, giving information a bit slower over the RT, not asking you to do things that you may not have come across before and generally keeping an eye on you to make sure you are okay.
I've found on busy LARS days that it really helps, but to be honest, most the time students are very good - in fact better than some people flying around with a licence...
