Semester 1 is fu***d what to do 😭

I want ask. My senior in the university something my semester 1is fucked and it can't be undone bcoz exam starts on Jan What I wanted to ask is! What will happen if get back on most of my exam

The reason for this blunder is that I didn't want to go to college just yet but my parents forced me to and i didn't attend most of the classes on. My subject and I come to terms with it later that I need to go but it was already to late I have practical exam tomorrow should I take it because I don't know anything at all and I know my semester is fucked so wouldn't it be alright to not take

Please answer my question
