Use formula

\scoring{formula=(NBC>0 && NMC==0?6:0)}

Ah. Somehow I missed formula= Thanks for kindly answering my stupid question :-)

Hi,

if I understand correctly, you turn a simple question into a multiple choices question

but it is written in the documentation that it is not possible (page 58 in english, 61 in french).

Does it work for you ?

I have to admit that turning a question from simple to multiple has not worked for me in the past.
However, this time it did. Either

a. The version of AMC that I am using now is more tolerant in that direction than older versions were,

or

b. I got lucky.

I don't know which it is.

but it is written in the documentation that it is not possible

C'est possible mais déconseillé. Le changement de question à questionmult ajoute un symbole (clubsuit) qui peut décaler la mise en page des cases et donc la détection est faussée. J'ai volontairement écrit vous ne pouvez pas au lieu de vous ne devez pas.

I understand. In my case, the line next to the question was short enough that adding a club does not create a new line. I am assuming that is why it worked.

Yes, that right ; no new vertical space added.

Thanks for all your answers. If I had this problem next time, I could try to see !
