Giving students credit for any and all correct answers marked

Added by S. McKay 8 months ago

Hi,
I made a mistake in a recent exam in which 3 answers (in a simple question) are correct. I changed it to a questionmult so as to pick up the other answers, but I don't want to penalize students who found one answer and moved on (it wasn't marked as multiple answer on the exam. I tried
\scoring{(NBC>0 && NMC==0?6:0)}
thinking it would give 6 points if a student marked one to 3 of the correct choices but did not mark any of the wrong choices. However it does not do that. Some get 6 points while others get 4 and others get 2.

What am I missing here? Is there something I'm missing in my formula? (I do use defaultScoringS and defaultScoringM for the other questions.

Thanks in advance,
S.M.

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.

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 !
