Using a fine felt tip pen of the Staedtler Lumocolour variety will help your drawing accuracy on the chart.
Whether you use a permanent ink or watersoluble is up to you in the exam: water soluble allows you to wipe clean any errors with the minimum of fuss, but beware sweaty palms doing this when you don't want it.
Do not use a chinagraph in the exam.
For the CRP 1 use a sharp pointed 2B pencil and take a sharpener and eraser in with you.
And then, as others have said, just get and do it!
(I don't think anybody would give you the waypoints ahead of the exam as this could be construed as cheating, but I don't see a problem with asking around of other peeps who have recently done the Nav exam to see if there is some kind of pattern in the routes they were given.)
I just don't want to fail like loads do because of something that may be out of my control!
If you prepare adequately, and draw accurately, then nothing is out of your control: it is you that is in control: think positive!
Good luck.
