Hi, anisa, welcome to the madhouse! We all panic here - a lot of the time - even when exams aren't looming.
If your daughter isn't taking it too seriously that might turn out to be a good thing - a little bit of confidence goes a long way (and she has you to do all her worrying for her!) Try not to wind yourself (or her) up too much over the next few weeks - cramming too close to the date can be counter-productive.
Have you posted in the Lancashire forum yet? They'll be able to help you out on what to expect on the individual papers - and advise where to get hold of some suitable papers to work through. You can then divide up 'weak spots' to be covered in the weeks leading up to the exam.
And remember - it's not the end of the world if she doesn't get the school you want. Bright, well supported children have a habit of rising to the top wherever they go.
I'm allowed to moralise on this topic because DD is heading to the Comp next month.
