Most banks offer career development loans, where you don't start paying until the end of your course. They're not like student loans however where you only pay when you're earning, it's a standard loan just at a better rate and with a deferred time for when you start to pay back. Failing that a credit card or overdraft if you have no savings?
Some courses let you pay termly, would this be possible so you have longer to find the rest of the money?
Finally if it were me I'd be hitting ebay with old clutter. Most maternity wear for example sells for £5-£15 (more for designer like Isabella Oliver) per piece, or bundles of baby clothes might make £10 a bundle. Old toys sell quite well too. It might not seem like much but you only need 150 sales at £10 a go to get your tuition fees together. Old DVDs, CDs and games can be sold on Amazon. I've had a big clearout recently to raise some baby funds, and I've made over £1200 in both October and November just with old clutter, nothing special or particularly valuable, so it might be time to have a good rummage for things you don't need that will finance your new life.
