My GCSE's aren't all that good mate, as they say, put them middle through the CV, get them interested in you before they read your qualifications. Usually they will think you are either good for the job based on personal achievements and work experience..

Army sums it up really:

Qualities outrank qualifications.

If you want a job, tell them all about you, and how you would make their company better.

end of the day, if you can do a job better than someone with a load of qualifications they will choose you.
