A vital part of the process is keeping a log book of all you hills and mountain experience. This will help the assessor establish your experience. The better your log the better your chances of passing.
Quality Mountain Days (QMDs)
Only QMDs will count directly to your logbook. A QMD is defined as at least 5 hours on the hill including time spent above 600m
You should gain experience in as may different mountain areas as you can. If you walk up the same hill by the same route ten times then it will only count as one QMD in your log book!
Only UK hills count but any other hills experience, including abroad should be logged as it shows a broader general understanding of mountainous terrain. Any hill time that doesn't qualify as a QMD should also be logged for the same reason.
Training courses should be logged in additional experience
Separate your log books
You should keep separate log books for different activities and in different conditions. For example QMDs in summer conditions should go in a summer walking log and in winter conditions should go in a winter walking log. Climbing should be logged separately from walking but if the climb is part of a longer hill day then that can be logged in your walking log. Again summer and winter climbing should be separated. It's good to also keep a log of your first aid training.
