Course subjects
Passing this semester
Every lesson opens with a concept video, then the problems that use it — because these are 2nd and 3rd year students meeting the subject for the first time.
Laboratories & field work
Where the equipment lives
Every experiment opens with its apparatus in 3D — rotate it, take it apart, then walk the procedure. Surveying adds a data processor per fieldwork: type in your own field sheet and it reduces the notes with the working shown.
