I'm planning to start RMR selection in september and was wondering:

How long it takes on average to complete training?
What is the ratio from selection to getting their beret?
Does being in holding troop make a notable difference?
Is it difficult doing university at the same time?

Inspiration ...

Im looking to join RMR Tyne in September, because im starting university in Newcastle then. I was wondering if it is difficult starting straight into uni and RMR at the same time. And if its difficult going straight into the selection weekend without any holding troop???
