How to plan course parts onto dives
Plan the course puts each part on a suitable dive, with theory and pool work on pool or classroom sessions and night parts on a night dive.
On the class page, press Plan the course. Waves places each part on a suitable dive. Theory and pool work go on pool or classroom sessions. A night part goes on a night dive (17:30 or later); if none is on the board, Waves adds one at 17:30.
