Brain turning to mush.....

I feel as though since finishing college my brain is not switched on as well as it should be! I think I may need to do some pre-uni reading...and I think I will give Martina Cole a break and have a read through some of my Anatomy and Physiology books! Also, I think I need to do some Maths revision...maybe GCSE bitesize will be the best place to start as I'm a bit rusty! Oh God...nerves are setting in!
