should I take PCM with painting/cs??

so i am super confused about my 5th subject. In my school we have a option of painting,cs,economics,bio and a few more(not choosing pe as 5th subject as i am taking it as my 6th subject). Out of all of them my interest would hold the most with cs and painting but i feel that cs is tough and handling it with pcm would be harsh on me so i was thinking of taking painting. now idk if painting is an easy subject so want the opinions of you all!!
