drop art???????

I think I should drop art but I don't know..... ok I'm gonna do a list of pros and cons if I drop art
ok pros:

• I'll have one less subject to worry about
• hsc assessment 1 for art is due on monday and I have no idea what I'm doing
• so if I drop art I don't have to do it
• no major work
• no need to be creative (I suck at that now I literally can not think of an conceptual ideas idk)
• more free periods 
• more time to focus on other things

cons:

• art is easy if you know what you want to do
• it's technically my best subject 
• I'm weak at all my other subjects too (chem bio english math)

I'm not sure what to drop out of chem, bio, english ext + math extension because I'm not good at any of them and I don't know if I'd be able to cope with them next year. I'm preeeettty certain I want to drop art at the moment but what if it's the wrong decision?? SHOULD I DO IT IDK LOL HELPPP
