English Portfolio

Hi, I have a few questions, and I am confused around this standard.

What is the key to creative writing at Level 2? Is there any important advice or are there any tips for creative writing; and what makes higher-grade (e.g. excellence) writing stand out from other creative writing?

I am a strong formal writer, so is it (practically) easier to obtain a higher grade through formal writing than creative? Does it matter, or would it make a difference, if my portfolio was entirely formal writing?
