Thinking of dropping a subject

Hi considering that there is about a month left till finals, my grades are horrible I get in math and bio low As and in physics Bs and I chemistry Cs and I don’t want to get started on Arabic idk what to do at this point I feel sooooo behind and like I don’t have time to finish anything and the fact that my chemistry mark isn’t improving is stressing me out so I was thinking of dropping it so to focus on the others subject and hopefully get a star in them but a lot of people are telling me that it’s simply and that I shouldn’t drop it and that I can get stars in everything and that there is still time and I am not sure if that is true considering the other subjects are bad to so help please
