If I could offer you just one piece of advice it would be this. Wear, Sunscreen.
As I am enfranchised to give as much advise as I please I will more usefully continue to tell you to go a learn how to read the approach plates.
I've seen people time and time again fallover on test because they missread a symbol or were otherwise distracted trying to re-check something on the plate that they failed to keep the a/c within test tolerances.
It will take hours but its free and you can do it from the comfort of an armchair. Get hold of the AIP for a start and learn the legends and how the approached/deps work. Then make sure you are fluent in reading either the Jepp or Aerad or other system that you will be using on test.
Honest - I know plenty of students who have been paying over £200 an hour airborne for me to take them through IFR chart reading and decoding when they could have done it all themselves the week before at home for nothing.
Good luck,
