All good advice here Okavango.
Another thing to keep in mind, that when it comes to doing a CPL course and test, you are being tested on your ability as a professional. So, from an early point in the course try to get into that mind set.
As has been mentioned here, make sure you are up to speed with all aspects of your aircraft type. Know all the flight profiles that you will be tested on down to a T, and demonstrate sound airmanship at all times when you are flying. Professional slick radio is also a must. Remember that the examiner will be looking for a professional attitude and approach to your flying as an overall package.
All the best with it mate.
