what am I not doing?

[She-Wolf]

hello all, me again. Not been on for a bit. I spent AGES on my second patrol, I got a legal kill and was then prowling around looking for the next one for hours - didn't want to have to go back with torpedoes still in the rack, so that was a fair time, and then waddya know, without any clues that it was unhappy, Windows threw a wobbly and I had to reformat C: drive. Tch. The game was ok as I had that parked on another logical drive, so only had to install the original game - but the saves were on the C:drive ( I have moved the whole My Docs folder now) so I lost the lot and have had to start from scratch. Well, I don't mind that. I went back to the Naval Academy, and as I have improved a fair bit I sailed through the Navigation test in about five minutes, only I have done it three times now, and surfaced each time once it is confirmed complete, and sailed a fair way back towards my starting point - but STILL it has not given me an exam pass, even though I got all the greens. What am I not doing I wonder? It passed me well enough before, and I wasn't half as good at it then. Hmph
