These days a good recommendation from your lecturers can go a long way, but if you are going to stand any chance when playing with a loaded deck, make sure you have a great hand. That means being an A student, getting a first, carrying out volunteer work, anything and everything to make yourself stand out. Make the good outweigh the bad, and you might stand a chance. Don't listen to others, if you want it, go get it. Yes you have a huge hurdle to overcome and the reality is, you might not make it, but at least you will have tried, and even if you don't make it, a law degree is not a bad degree to have. You will improve your future prospects dramatically. Go for it!
