Section Two of the exam
Posted 10 January 2004 - 08:44 PM
Section 1 - fairly straight forward
Section 3 - I am doing AI which my teacher says "learn the termonlogy and it will be ok"
He says the pitfall is section 2!!
I would agree, some years there are what I would class as simpler questions while other years ask you horrible stuff about arrays and parameter passing (see other topic)
Just wondered what people preferred! Are the parameter passing/array q's the hardest? They are for me!

Section 1 was no bad
Section 2 was prettty easy the programing n the stuff about parameter passing.
(I tht it ws easier than section 1)
Section 3 im doing networking, pretty boring, but really easy stuff!!

We have finished the course.

Ive just finished doing the networking unit and have started the investigations.
Hav u started ur investigation?
Posted 13 February 2004 - 06:05 PM
We have done all the practical nabs so I think that covers all the investigation work.
What are you's doing in the class up to the prelim? We are working through past papers! Has anyone been given out any other sample prelim papers etc?
I think the Computing exam is fairly straightforward with a good bit of revision! Section 2 will be where I am dropping most of my marks tho!

Width of data bus
Number of registers
Are there any other factors???And how do you explain the effect that cache has on it?

The ones you mentioned are really the main ones although you could also mention CPU clock speed - the more clock cycles per second, the higher the number of instructions which can be processed.

IF THEN ELSE ENDIF
What is a CASE function??? :S don't remember using that one!
And is the pass mark for an A about 70/100???

In 2003's Higher Computing exam (the one I did!) you needed:
- 69% for an A
- 58% for a B
- 47% for a C
- 70% for an A
- 59% for a B
- 48% for a C
As far as pieces of code you need to know - well you don't really need to know any of them. You need to be aware of the basic things like:
- Conditional loops - eg REPEAT..UNTIL and WHILE..ENDWHILE
- Unconditional lopps - eg FOR..NEXT
- Control structures - eg IF..THEN..ENDIF and the CASE statement
2003 Question 18e
One module of the program will take a tree name from the user and will count all occurrences of that name in the current list of trees. The module will return the number of times the name appears in the list or zero if the name is not found. Using psuedocode or otherwise, write a detailed algorithm for this process - 2 marks
The answer to this could be:
set occurrences = 0
FOR counter = 1 to maxarray
IF tree$(position) = tree_to_be_searched$ THEN increment occurrences
(REPEAT could be used instead of FOR)

In some programs, you might have lots of possible values of a viariable which you want to mean something. (eg a program where the user enters a number from 1 to 9 and display the number in text form (9 -> Nine) could use a CASE statement.)
If the number to be displayed it stored in the variable called input, this program would look something like this (in COMAL):
CASE input OF
The same output could be achived with IF statements but the code would be much longer and more complicated.

I don't think I could write that proper code in an exam!!
I find the questions hard where it says "Identify the parameters needed in design stages and state their types and how they will be passed" - thank goodness they are not asked every year! I think they were asked in 2002!!!

Steve what was yours like last year? Similar to past paper kinda questions? Some questions do repeatedly crop up I'd say.
Posted 25 February 2004 - 09:14 PM
And about the design of the code, you could write it in psuedocode - in fact they would probably prefer it, although I think you would get full credit if you did it in code - as long as it was right .
Have you still got your prelim to sit? All the prelims at my school finished two weeks ago, although ours are only on Unit 1 and 2.

Its the way the marking scheme is in computing! Do you need to right exactely what is said in the marking scheme or are there other valid answers??
Our teacher said he made the prelim himself, taking the idea's etc from Perfect Papers I think!
Section One should be ok. Section two, I never know if I have wrote enough to get the marks! Section 3 - I do AI - is fairly straighforward, recurring questions come up all the time
Posted 26 February 2004 - 09:28 PM
I thought it was not bad, the questions on software development were pretty hard.
Shud get my results next week.
Posted 27 February 2004 - 08:27 PM
I got section one back today and got 28/30.
I didn't think the prelim was too bad! Were a few tricky questions in section two, AI section was ok, apart from a few 4 or 5 marks I'll have dropped!
good luck to any one else sitting theirs!

I definetly think section two is the hardest. I do Multimedia for the optional unit which is mostly straightforward as the questions are always on the same things. The fact that section two is out of 40 is a b*tch as it is the section where I'll lose most marks - I did in my prelim.
Only 5 days to go now guys!
