How studying Physical Science on Keen works
- Add the course. Pick Physical Science from the catalogue and Keen loads its real unit list.
- Answer questions. Every answer updates a per-unit estimate of how well you know that unit.
- Miss something. Wrong answers are scheduled to return later, reworded, so you cannot pass on recognition alone.
- Watch the weak list shrink. Progress shows your weakest units first, which is the list worth studying.
