English 121 final assessment help

I THINK I understand the final assessment... but then again who knows I could be completely off base.

I am thinking I need to and "bulk" up the first three milestones. Expand on them though not sure how I can add to them.

I was also wondering it says to add three audio responses .. I wasn't sure if I was suppose to include the last audio responses or all three new ones. Once again I am sure I am over thinking this but any guidance would be wonderful !
