Can someone help me with my EXCEL SPREADSHEET. Pearson!

What's the issue?

I don’t know how to do it. Task was to use a project planning tool to show:
• timescales, including tasks and sub-tasks
• key milestones
• task dependencies.
Use today’s date as the start date of the project.
Design stage (3 weeks total):
• research existing user interfaces
• project proposal
• produce initial designs.
Development stage (7 weeks total):
• prototyping
• implementation.

Have you asked your teacher for advice on what to do?

We were told to do it all ourselves to get us ready for our exam in January
