So what is everyone doing to revise for this topic? Are you confident or not so much?

I would say the theory is fine. Pseudo-code becomes hard when it is an 8 marker. You've got one chance to do it and dont want to mess it up. We shall see!

I never touched the programming stuff with my teacher, so most people find this paper the easiest, but me!

How do you define a multi-dimensional array in python?

Is it possible in python, or do you have to use something like C ?

Does anybody have any good links which have nice revision notes? My PDF 2008 syllabus is the worst thing you can revise from with all unnecessary information you have to read,.

I don't know any of the programming stuff either (well, some simple stuff I guess...).

I found that you do this:
board = []
for i in range(3):
board.append([])
for j in range(3):
board[i].append(0)
print board
Which creates a 3x3 array named "board" full of 0s.

Apologies if you read before my edit, my previous way of doing it was rubbish!

This site is quite good as a quick reference for definitions etc. although rather vague:

Sorry, just realised the indenting didn't work.
It should be:
board = []
for i in range(3):
___board.append([])
___for j in range(3):
______board[i].append(0)
print board

(where ___ is indent!)

http://ge.tt/5lCxEwi1/v/0?c there you go.

Some of them might have some grammar/spelling errors which i corrected when i printed them. I would check everything.

Do you have any python stuff?

Thank you very much.

For Python, I'v been going through the spec. and my revision guide trying to work out what we could possibly be asked to write in a programming language. So far my list is:
  • 1D and 2D arrays.
  • IF and CASE/SELECT statements.
  • FOR-NEXT loops, WHILE-ENDWHILE loops and REPEAT-UNTIL loops.
  • Subroutines including the passing of parameters and return value functions.

There are more, but I'm afraid I haven't got very far in my revision yet.
Last night I worked out how to do arrays. I have no idea whether this is the correct or best way at all, but it seems to work. I've written out some pseudo code examples of arrays and then recreated similar ones in python. I know there are simpler ways of doing it, but in all of the examples of questions I've seen they seem to want you to use a for loop :/
(Sorry they're handwritten, hopefully you can read it and work out what I'm going on about ).

If you like I can also send you my typed up notes on the course, if you wanted to compare and combine notes?

Guys, im thinking we should all get into a google hangout or skype group message, then we can all leave it logged in and when someone needs help, post in there? Easier than coming to here, plus we could all discuss certain aspects of the unit? Anyone think that sounds good?
