the SWOT workshops are there for a reason - people students demand them.
I have found that my friends who have recently finished school, don't find a "report writing workship" all that helpful.
but many people who are not familiar with university forms of writing, such as mature age students, people who didn't do well at english at school, international students have found them helpful.
All those other ones like mindfulness, stress management and so on, if it interests you, and you have the time, i don't think you will be disappointed.
you get lots of free stuff
and you get to meet new people
and you will know where all the resources are when you may need them in the near future or a help a friend out who might be stuck in a rut.
good luck!
