Help!!!!

Help!!
I've just realised how difficult becoming a lawyer is really going to be! And I haven't even got my AS results jet!!
I'm in a panic. For at least two of the universities I want to apply for I need to take the LNAT test, and then my results will be sent to those universities that want it. Simple enough? I thought so.
I went to look today to find out when I can take this test, hoping to get it over with this summer, only to find out that I can't take it until September! And, that I have to book and pay for it online!
So, it was with great trepidation that I decided to take the practice test, only to realise that I didn't have a clue what I was reading and that I was then expected to answer questions on it that seemed to have no relevance to the passage I had just read. I got through the 30 questions, barely, only to then have to write a 700 word essay on an extremely random subject.
I chose the one that wanted my response to the view that education prepared young people for the world of work!!! 20 minutes and 450 words later I accidentally pressed escape and got rid of the whole thing!!!
I had wrote down my answers to the multiple choice bit, so I checked my answers and discovered I had only got 13 out of 30 right!

As you can tell, I am not happy. Nor am I very sure why I still want to become a lawyer! If anyone knows of a good reason for becoming a lawyer it would very much be appreciated.
