Don't go to uni then. There's more to life than grades. Like you say everyone seems to go nowadays and it has lost a lot of its value. Getting in 30k of debt to do sociology at Nottingham Trent isn't really worth it. You're better off doing an apprenticeship or just getting a job at a company and working your way up. I would just try to get through your A-levels and pass as for most decent jobs/apprenticeships you need A-levels.
