can i add an extra 6uoc to my degree to go on exchange?

im currently doing research on exchange possibilities for next year. i only have 18uoc that i can use on exchange and was thinking about going to japan but i read quite a few of them require you to study 24uoc.

im doing bcom degree where there is 144uoc but i was wondering if i can add another 6uoc to my degree = 150uoc? or is there any other alternatives yall can recommend?

asking here on reddit because im not sure who to ask @ unsw and when i submit an exchange inquiry online it just refers me to the moodle... which doesn't answer my question.

also if anyone has gone to meiji uni for exchange or japan in general could i maybe dm u some questions? thx!
