AS Computer Science AQA Paper 2 14th June 2016

You've been taught an oversimplified version of the law. "Swap All operators" only works if there are exactly two operators. I suppose there are two operators here but the two operators are "A" and "A+B", not "A" and "B" as most of your classmates must have naively assumed.

To test it out:
The original thing is (A+(A+B)''
My simplification is A'.(A+B)
Your simplification is A'+(A.B)

If A = 0 and B = 0:
The original thing is (0+(0+0)'' = (0+0'' = (0+1)' = 1' = 0
My simplification is 0'.(0+0) = 1.0 = 0
Your simplification is 0'+(0.0) = 1+0 = 1

I could carry on but you get the gist. Your expression outputs different results to the original.

There needs to be an END IF after MOV R2, #69

****, your right. Thanks for that. Possibly looking at a Max of 20 marks lost , Mid B High B I reckon.

Anyone know what the paper was out of? swear it was out of 72?

The front of the paper said it was out of 75

Do you lose a mark if you dont put HALT?

Yeah thought so, last year it was 60. Probably just a thing that comes with the new spec.

70% = 53 Marks - A

I might actually have a chance. Good luck everyone and if anyone has Mechanics on Friday , it was good whilst it lasted ...

Do you think 70% will be an A?
I thought (comparing to other years) its around 75% or so
I dunno lol
but they should be lower anyway this year because it's a new spec and AQA need to prove that the same amount of people can get A's lol

Yeah I would say 70-80%, tbf it all comes down to the first paper, i ducked it up.

What did people get for the extra number of bits or bytes when increasing the colour depth?

1 extra bit I put

I put 1 or 2. Can you remember how you did it?
