    Think I did my weird tbf.
    I don't know if mine is right or not. Hopefully we should both get some marks for some tables, even we get the rest wrong XD

    What were the two reasons for using a digital certificate? I could only think of can prove that a message is genuine?
    To check for integrity (data hasn't been corrupted or modified in transit) and authenticity (the sender is who they say they are).
    The paper was nice. I suspect I may lose marks on the first SQL question this time, as the mark schemes have typically been quite stringent as to what they accept for similar questions in the past. Other than that, it was a nice paper. The 7-mark question was lovely.

    Either way, that's all my exams finished!

    Why are you assuming there aren't any C grade students on TSR?
    I've been reading this thread and everyone here seems pretty smart! :P
    I can add the C grades if anyone would like me to! LOL

    So, though i'd join in on the discussion... Everyone seems to have found the trace table hard but I thought the trace table was pretty good, just required alot of time to trace it out but you have 2 hours 30 anyway!
    So, question time -

    Firstly, for the two reasons for digital certificate, i said to check it was from the original person and that it hadn't been tampered with which is what everyone else is saying but would the mark scheme be harsh and say the words "integrity" and "authenticity" must be used as I didn't use those words but explained the same thing

    Secondly, for the hashing question (the one with the database, not the digests) i'd never learnt about it due to it not being in the book and I didn't know it even existed until that morning, I got 751 for both which I'm happy with but what was the correct answer for stopping a collision? I just said some BS about multiplying it by 10 to find a number not already allocated...

    I put that you could either use Closed Hashing - Which would put the data into the next available location, or Open Hashing - Where it would start a linked list within the same array position using pointers to point to where in the memory the other data is (so it would be in the same hashed number position as any other data with the same hash value but in a different memory location)

    (If that made any sense )

    Ah that makes sense, i'll keep that in mind for my uni course
    (i'm really quite annoyed how terrible the AQA endorsed text book actually is though, thought i could rely on that but I guess not )

    I don't think there is any real time, I think we just get told the moderated grade in August with the COMP3 grade (at least that is what's happening with my sixth form)

    We were supposed to get our project marks this week but my college have decided to change their policy so you only receive your marks/grade after aqa have moderated it.. -.-

    Haha, my sixth form is refusing to give us our grades as well so I share you're pain! I was told my project was an A* but then it was remarked and they won't tell me if it went down or not because the grade wasn't final due to moderation -.-
    Any idea on how you did?

    Oh nice. I'm surprised AQA are allowed to disclose that without breaking the data protection act though. Congrats though, that's awesome!

    I wish I'd done a bit more revision for the exam - I left the hall with a lot of confidence, but I was a mark off an A?!?

    Yeah, I suppose it was odd that my maths teacher was giving me this information. Also, the fact that it was disclosed to a private company as well. Maybe there was something in the AQA terms and conditions we didnt' notice?

    > Your information may be passed to and used by other companies within the AQA group. Save for the AQA group and agents working directly on our behalf, AQA will not pass on your details to any third party unless you give us permission to do so, or AQA is required to do so by law.

    It doesn't look like they're an AQA group company - email your school and ask? It'd be interesting to find out how.

    This was a damn long time ago haha, I don't think anyone here remembers any of the questions. I only remember one, and that involved using "media queries" as an answer.You're better off asking the 2016 thread as they'll probably be doing 2015 as a mock (presumably like you).
