About points...
We associate a certain number of points with each exercise.
When you click an exercise into a collection, this number will be taken as points for the exercise, kind of "by default".
But once the exercise is on the collection, you can edit the number of points for the exercise in the collection independently, without any effect on "points by default" as represented by the number here.
That being said... How many "default points" should you associate with an exercise upon creation?
As with difficulty, there is no straight forward and generally accepted way.
But as a guideline, we tend to give as many points by default as there are mathematical steps to do in the exercise.
Again, very vague... But the number should kind of represent the "work" required.

About difficulty...
We associate a certain difficulty with each exercise.

But once the exercise is on the collection, you can edit its difficulty in the collection independently, without any effect on the "difficulty by default" here.
Why we use chess pieces? Well... we like chess, we like playing around with \(\LaTeX\)-fonts, we wanted symbols that need less space than six stars in a table-column... But in your layouts, you are of course free to indicate the difficulty of the exercise the way you want.
That being said... How "difficult" is an exercise? It depends on many factors, like what was being taught etc.
In physics exercises, we try to follow this pattern:
Level 1 - One formula (one you would find in a reference book) is enough to solve the exercise. Example exercise
Level 2 - Two formulas are needed, it's possible to compute an "in-between" solution, i.e. no algebraic equation needed. Example exercise
Level 3 - "Chain-computations" like on level 2, but 3+ calculations. Still, no equations, i.e. you are not forced to solve it in an algebraic manner. Example exercise
Level 4 - Exercise needs to be solved by algebraic equations, not possible to calculate numerical "in-between" results. Example exercise
Level 5 -
Level 6 -

Exercise:
Im Jahre wurden mit privaten motorisierten Fahrzeugen ingesamt seO zurückgelegt. Angenommen diese Fahrzeuge wären alle Elektroautos mit einem durchschnittlichen Energiebedarf von EzO pro szO. In welcher Zeit würde dann das Kernkraftwerk Gösgen bei PO Nettoleistung die notwige Energiemenge liefern?
Solution:
Geg s_ seO se E_ EzO Ez s_ szO sz P PO P % GesZeittsis % Die notwige Energie pro Strecke eines Elektroautos beträgt al hat E hEF fracEzsz hE. % Für die seO ist folglich eine Energiemenge von al E_ hat E s_ EeF hE se Ee erforderlich. Diese Energiemenge liefert das Kernkraftwerk Gösgen innert al t fracE_P fracEeFP tF fracEeP t approx tS. Das sind rund tdty. % t tF &approx tS
