EGDR,
Yup, I failed instruments last sitting, so I'll see you in October!!
I think I got scuppered by those tacho questions too. I hadn't done anything on them before so I had no idea what the answers were. I will definitely be reading up on them now though.
If you get your hands on any good feedback questions for instruments would you mind emailling them to me? Thanks a lot. I'll send you any I get as well.
Good luck for the re-sit.
Cheers,
Billy M.
