How to evaluate not selected p-answers

[janmaterne]

With K-questions you could skip answers by not selecting a column.
These missing answers don't have negative points as consequence.

With P-questions you can't distinguish between "skipped" and "not selected, because it's wrong". How to evaluate not-selected answers?

• use as "wrong" with negative points
• use as "skipped" with no impact

[gernotstarke]

open or left-out answers in P-Questions are treated as "zero" ("skipped"), having no impact

We should clarify that in the description of the exam, if it's not clear enough (... PR welcome)

There is an extra issue for that, which describes the problems we currently have in the description and examples.
