u should also know the difference between (validity) and (verification), u will alwaaayyysss get a question concerning these 2 and the questions are usually are atleast 10 marks in total,
u also need to know how to design certain screens like a screen at a supermarket or banker, which is usually easy, and know how to "play" with a robot/turtle. :)
When they talk about me they say I be trippin
What they say about me doesn't make me mad 
I think they hatin cause they see me when I'm rollin
Man I can't help it that they really doin bad  =P

Big cars, Big wheels, Big chains, Big pimpin', Big money, Big Dreams ;-)

Guys www.teach-ict.com is an amazing site you can find everything, There were things I didnt understand until I read from there.

And an advice to do as much past papers as you can in addition to checking your answers from the mark scheme which is useful.

Everything is on www.freeexampapers.com for people who dont know

Q3) why models are better than the real thing
A) 1) Cheaper
2) o/p may be dangerous to human
3) waste of materials
