AQA Psychology Paper 2 BioPsychology question

Just been having a little look at the spec, and I am confused by biological rhythms.
I know that sleep/wake cycle is named and we have to know that, but I don't know what we need to know about ultradian / infraradian, other than the fact they are more than 24 hours and less than 24 hours.
It seems so vague but I'm not sure what I need to learn.

infradian (need to know eg of menstruation cycle) - McClintock
ultradian (need to know eg of stages of sleep)

Do you think I need to be able to evaluate them?
