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.

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:
Eine Vakuumphotozelle wird nacheinander mit Licht unterschiedlicher Wellenlänge lambda bestrahlt. Mit einem Voltmeter wird festgestellt dass sich zwischen Kathode und Anode jeweils eine andere Spannung U einstellt.mm Für die verschiedenen Wellenlängen des Lichts ergeben sich die folgen Spannungen: center tabularl|ccc toprule.pt lambda in nanom & & & U in milliV & & & bottomrule.pt tabular center Ermitteln Sie unter Verwung der Versuchsdaten die Planck'sche Konstante h.
Solution:
Es gilt: E_Ph frachclambda. Für zwei verschiedene Wellenlängen lässt sich die Einstein Gleichung des Photoeffekts in folgen Formen schreiben: frachclambda_ e U_ + W_A und frachclambda_ e U_ + W_A Subtrahieren der Gleichungen ergibt: frachclambda_ - frachclambda_ e U_ - e U_ myRarrow h fraceU_-U_cfraclambda_-fraclambda_ apx .^-Js.
