Here is the Extended Project Portfolio (FMP). Make sure you read through all the document and familiarise yourself with the requirements.
Firstly though look through the Proposal and have this finished for the first week back after half term for a pitching session. Which is on pages 6, 7 and 8.
After the proposal has been agreed and signed off you can work your way through the portfolio, reading the guidelines and advice as you go to ensure you complete the Extended Project and all the criteria.
