Thanks guys
Thanks for the advice guys and pleased to hear the feedback is useful. I have been trying to learn the manuals but there's so much I'm struggling to get high marks in tests. I have of course done end of chapter questions as I've gone along but the reality is that I've kept putting off the feedback until I had 'learned' the material. Reality is there's too much to 'learn' in the time you get to revise and some stuff I learned as I went along doesn't seem to have been retained.
Ergo the feedback may be my saving grace!
Thanks for the advice,
