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.
When you click an exercise into a collection, this number will be taken as difficulty for the exercise, kind of "by default".
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 -

The following quantities appear in the problem: Masse \(m\) / Energie \(E\) / Aktivität \(A\) / Leistung \(P\) / molare Masse \(M\) / Stoffmenge \(n\) / Zerfallskonstante \(\lambda\) / Anzahl \(N\) /

The following formulas must be used to solve the exercise: \(A = \lambda \cdot N \quad \) \(m = nM \quad \) \(P = A \cdot E_1 \quad \)

Exercise:
Der russische und später britische Nachrichtienstler Alexander Litwinenko wurde am . November mit Polonium mit PO Strahlungsleistung vergiftet. Es wird davon ausgegangen dass das Isotop isotopePo mit TO Halbwertszeit und MO Atommasse seinem Tee beigegeben wurde und er anschliess innerlich der pro Zerfall EeO starken upalpha-Strahlung dieses Isotopes ausgesetzt war. Wie viel Masse Polonium hat er folglich unwissentlich zu sich genommen?

Solution:
Das radioaktive Polonium hatte A fracPE_ fracPEe A Aktivität. Aufgrund der Halbwertszeit entspricht das N fracAlambda fracAfracln T fracATln fracAlam fracA Tln N n n vorhandenen radioaktiven Polonium--Isotopen. Diese haben m N m_ fracATln m_ fracPTE_ ln m_ N M m approx mS mP- Masse. m fracPTm_E_ ln mS mP- Ausrufbox Litwinenko ist Tage später am . November in London an den Folgen der Vergiftung gestorben.
