    We have been told that they will have a choice, but this is nowhere in the guide.  I have my students learn both and then hope that the IB will remember what they promised.

    Dear John, In an exam will an SAQ ever specify to 'describe one effect of one excitatory neurotransmitter' or will it give an option such as 'describe one effect of one excitatory or inhibitory neurotransmitter'? Thanks!
