Concerns about clearing choice

Hi all,
Got my results yesterday and do to circumstances at home I've achieved far below what was required for my firm choice at Warwick. I have, however, managed to gain a place in clearing for the Biology course at Bangor University even though my grades are far below the entry requirements. This is great, however I'm still unsure as to whether I should consider resisting my A Levels. Realistically I know I'll be able to achieve far above my current grades but all things considered it's not something I can guarantee, as the future is always unpredictable. I'm completely lost, really. I do like Bangor, but it's a decision that will influence the rest of my life, and I have no idea what the best option for me is. The negatives for each option are all plentiful, and I'm struggling to see a situation where I'm really happy with the decision I made. Anybody got any tips or past experiences like this?
