Always resits mate! Even if you don't you can still get a good job don't despair! If you've got the drive/ability then at worst you just have to start bit lower down the ladder. I had f*ck all qualifications when i started, now IT Engineer for worlds richest oil-company and a decent armory lol. and i didn't start doing this until about 23-4, took 4 years of sh*t paid work to get there.
