Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016

What did you guys roughly put for the algorithm
I put this:
Input NumberA
If NumberA is in numbers() then
Output "taken"
Else
Numbers(NumberA)="A"
End If
NumbersNot=numbers(A-b-c)
Output numbersnot

This may be totally wrong but i gave it a shot the rest of the paper was decent
Bit busy atm but something like this.

A huge generalisation...

Input number

if number !== numbers(" "):
count = numbers(" ").count

else:
numbers(number).append(A)
like before....

output

Oh yeah I was going to say earlier. Not sure if you all knew but there is three assignments for A452 and A453 (you only do one on each obviously). One of the A452 ones had the answers in a book (even if the students didn't know) and now the exam board are skeptical about accepting their grade. I feel sorry for them.
Do you know which one? Hope it wasn't mine

Something like:

Start
Input number
If numbers(number) = "" then
Numbers(number) = "A"
Else
Output "taken"
Count = 0
i = 0
While i < 101 then
If numbers(i) = ""
Count = count + 1
i = i + 1
Output count
End

With line numbers aswell xD

Our teacher wouldn't tell us which one but she just said it wasn't ours.

I did that coursework & we used the book; they're not sceptical about it (they've issued an official statement saying it's fine) because before we used the book while we were doing our coursework my teacher rang up and asked if it was OK. They said they were aware of it and using it was fine, it's just like using any other resource you find in the research task.

A couple of years ago some coursework was pulled though, glad that wasn't me I'd cry!

if number !== numbers(" ";):
count = numbers(" ";).count

else:
numbers(number).append(A)

I did like:
START
INPUT number
IF numberList(number) = 'A' OR 'B' OR 'C':
OUTPUT 'taken'
ELSE:
numberList(number) = 'A'

FOR numbers IN numberList():
IF numbers = 'A' OR 'B' OR 'C':
numbersTaken = numbersTaken+1

OUTPUT 101-numberTaken
END

:S do you think that would be right?

i did:
input choicea
if numbers(choicea) = " " then
numbers(choicea) = "a"
else output "taken"
end if
numberstaken = 0
for i = 1 to 100 do
if numbers(i) = "a" or "b" or "c" then
numberstaken = numberstaken + 1
end if
next i
end loop
numbersleft = 101 - numberstaken
output numbersleft

it's quite a roundabout way of doing it (should've just calculated the taken ones by checking if they're empty strings ) but i'm pretty confident that it works

I put:

INPUT choice ------------------------------------------------------- take user's choice
IF numbers[choice] == '': ---------------------------------------- if index chosen is empty
THEN numbers[choice] == 'A' ----------------------------------- put user's letter in it
ELSE IF numbers[choice] =/= '': -------------------------------- otherwise,
OUTPUT 'taken' --------------------------------------------------- tell them it's taken

INITIALISE count ------------------------------------------ to count how many numbers are still available
FOR x in numbers: ------------------------------------- for each element in the array
IF x == '': --------------------------------------------------- if number has not yet been taken
count = count + 1 ---------------------------------------- add 1 to count
OUTPUT count -------------------------------------------- output how many number shave not yet been taken

Haven't seen anyone talk about this yet. I thought I did really well on it (better than every other exam I have done so far) except I am annoyed that I messed up the Binary addition question because in my head I know how to do it.
Sad times when you put 0217 for the UserID question. Worst exam mistake ive ever made...

I did end up getting A in both of my coursework. However it was then calculated that I would need 80/80 in the exam to get A* overall...

And yeah... there were some problems later of me being totally outraged at my teacher - killing myself working towards my coursework just to find that OCR doesn't think getting A is suitable enough for an A*...

so yeah....
Are you aiming for an A*? 80/80 I wouldn't have thought so unless you were only just in the A or something

Man... I never achieved anything lower than A* in mocks or any exams.

I am doing Computing for A-Levels too, so it is embarrassing for me to show up with an A when I am an A* student.

What can I say...
11. (Original post by *JustARandomGuy*)
I messed up the interpreter question. I wrote it read/scanned line by line (even though I knew it was wrong) but it was more of a guess to try get a mark.
This isn't wrong, you're correct. I wrote this also.

I'm amazed... A guess is actually correct for once

Anyone know the answer to the query criteria question...?
(Year = 2015) AND (Catagory = "Comedy")

Anyone know the answer to the query criteria question...?
It was just asking for you to write 2 statements such as

(X = 0 ) and (Y = 3)

Cant remember the actual fields used.
15. anyone got predictions for grade boundaries? I wanna get an A* but I got 80/90 in coursework and I think I got 60ish out of 80 in the paper
16. I got 86% in both coursework sections which is an A*. Bearing in mind the coursework is 60%, you should be able to maintain that if you got a fairly decent mark in the exam. 60/80 is good, 56 was an A* last year so you should be alright!

80/90 is like 40/45 on both, which are just missing the star boundary. I'm not sure what the paper boundaries are, but I'm not sure if that is enough

Take what I said with a grain of salt tho lmao
