A bit worried. What does my profile need? GEP applicant 2016-entry

Here's my info/profile: I'm in the third year of a Business Management degree at Sheffield University and have been working in a nursing home as a care assistant at weekends since February 2014. I've also been a Samaritans volunteer for a year and have had paid work experience in an unrelated field for a year before attending university. I've been looking at the profiles (on TSR, Reddit etc.) of a few of the people who've been rejected and it's frightening and disheartening, to be honest. I'll be applying for 2016 entry and was wondering what you guys think it would be useful to do over the next year based on your experiences. What would you do if you had a year? By the way, I'm 23 years old and will be applying for the first time to 'any discipline' courses like the one at Newcastle (I'm aware of the UKCAT score needed)
