    Got a c1 exam tomorrow, need to just be sure about one thing. I do MEI and in their mark scheme when you draw a cubic graph it has this note: No section to be ruled;no curving back; condone slight ‘flicking out’ at ends; condone some doubling (eg
    erased curves may continue to show). What do they mean by no curving back just so I make sure that I don't do it
