Improve your drill. Seriously. Irrespective of how good it is now, make it better. Be sure of >proper< timings/pauses, compliments on the march, saluting at the head of a formation passing a dais etc. If you haven’t been reprogrammed with the ‘new’ about-turn-at-the-march, sort it[color=#0000bb] now[/color].
Practice the extended SMEAC briefing approach, in task groups with you as leader and also as a team member (ideally with people you don’t totally know…similar to OASC, but much more so).
Be confident (or become more at ease) with oral briefings, again as an individual and as part of a team.
Aim to have your kit immaculate from the start, and to improve during the course. Thread a flat elastic around/through the v-neck of your jumper, with the knot stitched-down on the inside. And no, your shoes aren’t perfect yet, try harder. Seriously consider taking a good steam iron, and some form of improvised ironing board. Remember pressing/ironing cloths, and be happily prepared to rewash uniform in the utility rooms (it’s impractical to take 5xlong+5xshort-sleeved shirts). As well as the kit-list, take washing powder, teabags, spare coat-hangers, hand-mirror, A5 wire-bound notebooks, A6 blank postcards, pens/pencils and a sense of humour.
Don’t be tired before you attend. Try and improve your own personal stamina, not through some crazy exercise regime, but by building-up energy in reserve for what is an extremely-good but demanding experience.
Know the key elements of ACP4, 1 and 2, and the common-sense aspects of ACP5. Get to know every member of your course from Day 0, and treat it as a team event where the only person you have to be better than is yourself. Course staff are excellent, genuinely supportive and well-suited to their roles: they deserve a massive pat on the back.
