Kyyle,
Out of curiosity who is providing the scholarship?
These opportunities don't arise too often so give yourself the utmost possibility of attaining a place. At a conservative estimate the cost of a helicopter CPL is £50k then to have a look in at getting a job in the offshore industry it's a further £50k. The reason I allude to this is for you to appreciate what's on offer to you. I would imagine as the candidate pool diminishes the questions asked by the intwrview panel will become harder. Learn basic rotary wing aerodynamics also learn a little about the type of helicopter you're going to be training on and the primary control functions. If you're truly serious about a career in commercial helicopter flying get studying now and impress the people who might perhaps invest in you.
Regards
MF
