That skill should have been taught in OW. Practicing that skill to perfection, only makes sense to me. Odds are, the same emphasis on neutral buoyancy will be given in OW and AOW by the same instructor. If you're having issues with your trim and buoyancy coming out of OW, then you might want to change instructors.but the advice to nail down the skill before taking the course that teaches that skill seems a bit odd to me.
