    Do you remember the grade boundaries from last year?

    And lol i got an E last year, so anything i do this year will be better.
    A 70, B 60, C 50, D 41, E 32. From what everyone is saying it sounds like this one was easier so I would expect them to be slightly higher than that this year. Hope it went well for you all!

    That's exactly what i wrote too, but wasnt the question just to tell the difference between the two?
    "Analogue signals are electrical signals with values that vary in a continuous manner while digital signals are electrical signals with values that vary in a discrete manner" - Is what I put.

    Yeah the question was 3 marks i think and was just to say the differences. For that FSM question did you say there was 5 possible states aswell?

    Its looking like Section A for me is :

    Section A : 29/31
    Section B : 18/19
    Section C : 9/14
    Section D : 20/36

    76 is probably a B

    Does anyone remember what the last 2 marks of Section C were?

    Yeah i got 5 states. I probably just scraped a B so I'll have to do alot better in COMP2 and COMP3

    What did you guys get for the storage of a 65536 colour, 16x16 resolution image?
    Can someone tell me how they worked it?

    Thought it was a pretty good exam. Got all of those except 4 sample resolution, I think it was 12 but they mislead you by putting them in 4 bits.

    Last question was hard but I eventually got there by using two for loops and 4 if statements that checked if a flip was possible, then if they were appended the coordinates to an array and printed the array.
    Instead of using two for loops, you can do one loop from 1 to boardsize * 11

    log(65536) (base 2) = colour depth = 16

    16 * 16 = screen resolution

    colour depth * screen resolution = file size

    please no one tell me I'm wrong, plz, plx, pls.

    So that Comp 3 book thing, can I get in on that? I think I'm going to need to destroy that paper and hopefully I'll get a good night's sleep before it.

    Then file size divided by 8 to get bytes.

    2^16 = 65536
    So->
    16x16x16= 4096 bits
    4096/8 = 512 bytes

    Isn't 278 impossible in two's complement. Since the left most bit is -128

    MSB is the sign bit, the second most is 64

    I got -76 or something similar - the most significant bit is -128, then add the placeholders where there is a 1

    Meaning 278 is impossible right? In 8 bit two's compliment anyway

    EDIT: -76 as the guy above me got, is the same as what I got
