Thank you to all of you for your replies to this.
You've helped me to see the bigger picture and not worry too much about my score and instead keep pushing to achieve my lifetime dream. Ofcouse thats what you would do, but after results like this you feel disheartened but this has opened my eyes alot more!
Thank you for all of the detailed responses too...they were fantastic!
I wish you all the best!
Climb350, just go through some GCSE books, anything would help just to get the basic maths going. I never used any software.
