Should I take pcmb

Tomorrow is my pre board 1 ptm… and we are gonna get to fill the form of which stream to take in 11th.. Maine itna too soch liya hai ki I am gonna take up pcm.. but should I also opt for bio? Aisa Nahi hai ki I don’t have interest in science.. I find it quite interesting (even the topics from class 11th science) but I am puzzled if i will be able to handle it in 11th or not.. my father is saying that I should take Pcmb (he also had it when he was in school). But i am confused whether I should take it or not..
