no there isnt.
ur best alternative would be to download the past papers, along with the ER(examiners report) from the board of sudies website

I think...
INPUT is what goes into a function. What you give the program.
OUTPUT is what comes out of a function. I don't think it necessarily has to be visible... so, say, if you have a program which adds two numbers, but doesn't display the result, the output is still the result. I might be wrong.
and PROCESSING is the function itself. Might be mathematical or converting something into a different form. Processes are the things which make an input into an output.
Does this help? Eh.

yeah but say for a game im creating i wouldn't have a clue how to identify the inputs for a game.
like for say a frogger game to get to the other side. what inputs would there be ?

You can read minds?
ummm a frog... road... cars???
not sure bout inputs either.. i thought it was the stuff that is needed to acheive and objective... for instance u need a plane to get across to hong kong (unless your a illegal immigrant) u need fuel, an airport... the process may be driving the plane, taking off and landing whilst the output is you arriving at Hong Kong...

yes
but how do u come up with these ?
it never occurs in my mind :/

doesnt input include things that are part of the internal processing, rather than just the users inputs? that is what my techer told me.

in terms of computer programs
input - list of data that is inputtted into computer (eg : numbers. words etc..)
output - list of outputs presented or in other words the way the results of the processing is presented
processing - rules / instructions taken according to the input
i dunno this is wot i vaguely remember from last terms test... correct me if im wrong?

inputs - data entering the system
processing - how the inputs get transformed into the output
outputs - the output =]
even with that i can't really identify correctly when given a scenario

Imagine you are the person that is using the system.
Whatever you punch into the computer could be the input. Then looking at the system, what the system does to what you've entered can be part of the process. Whatever that throws back at you will be the output.

it takes practice... do lots of questions on ipo stuff and ull get the jist
try to identify wot is inputted (ok that mite not give u a good definition but no other simple way to put it) into the system as the input
wot this input is done with (process)
the result / way the input is presented after being processed
look thru lots of old computer studies 2 and 3 unit books i know i got the hang of algorithms with them coz of the millions of questions they provided... mayb it could help u with ipo charts / diagrams

or try it when you're, say, foruming 
you could look at the system as being things which input, things which output, and the CPU
input things are like the mouse, keyboard, touchscreens, tablets etc
output things are the monitor, the printer, speakers etc

Does anyone here know how to write bubble sorts, and etc?
i need like just some help on the search and sort area of algorithms.

u may want to check out "methods of algorithm description". laz uploaded it onto the forums here...http://www.boredofstudies.org/community/showthread.php?s=&threadid=6467

Exactly, sunny.

You also have to remember - that in some cases it is no worse than using more complex methods. And in many is actually better. (Note - Selection and Insertion are not 'really' 'complex' methods...)
EG: If you are sorting only a small number of items, then the bubble sort is perfectly fine. However, in this same situation, overhead from a more complicated sorting routine (like using recursion in quicksort) becomes greater than the time taken for something simple, like a bubble sort, to get through the same list of items.
However - we only deal with three fairly simple routines in SDD anyway - so there is no need to worry about anything complicated (like quick or merge sorts...)
