Art gcse next week!!!!

Hi everyone, I REALLY NEED YOUR HELP!!!
On Thursday and Friday (15th and 16th) of March 2018 I will be sitting my GCSE Art, final 8 hour exam. My topic ( chosen title of the syllabus) is EMBELLISH. Even though I chose it my self I am having major trouble with ideas or what to do. It is way too late to change the topic, so any ideas at all would be very appreciated for what I could create to achieve the GCSE at all! At the moment I have no confidence I will come out of this exam alive!!! I am aimed a C-B grade and would say BIRO and PENCIL work are my best chosen medias BUT Paints (especially for portraits I'm not amazing at!)
Any help will be greatly appreciated!!
Thanks
