Hi all,

Here's my attempt at a postmortem on the exam. 
https://docs.google.com/document/d/1FvMdntL-BZZ_rRREf2cgPgWyt1siiBwVm0vHJ3vcYfI/edit?usp=sharing 
I haven't yet had time to copy all of my answers and comments into the document, but I'll try to finish it off soon.
Your (polite) comments are more than welcome!

Simon

A6: Agree it doesn't really fit BUT if you upgrade to say "Windows 10 Anniversary" a Windows.old is created as a BACKUP of the old OS and you can RESTORE back to the old OS if you want.

I agree with A6 – it doesn’t seem like backing up - how will this help recovery if the HDD fails?

And it’s doesn't seem like archiving as the data is not removed (physically at least) from the primary system.

    In all seemed like a very approachable paper overall but couple of thoughts:

    A6 - I think the answer is "None of the above" - technically it is neither

    B4 - I was concerned about the language - "hash function" as opposed to "associative arrays (or dictionaries or hash tables)". I covered it with students but it wasn't something we focussed in in revision as I didn't consider implementation i.e. hash function to be part of the study guide.

    B2 I thought unnecessarily heavy on the written side; could they chosen any longer variable names. I'd like to see someone indent the pseudo code in a meaningful way and fit the following line in the space provided in the paper:

    IF EmployeeNumber < LowestEmployeeNumber THEN

    A2 may be confusing for some ESL students. It tests your comprehension of riddles rather than knowledge of the Quick Sort.

    Feeling of students was cautiously optimistic.

    Regards

    That's how I read it to Trav

    I read it that the numbers go in the location corresponding to their remainder after being divided by 5, so:

    [0]
    [1] 11 (Already given)
    [2] 17
    [3] 23 | 8 | 13
    [4]
    [5]

    Obviously this is vertical in the exam, so the top 3 boxes under index 3 are filled.

    Would that have been correct? I agree that I'd never seen a question like it before, but I suppose there are only so many ways you can ask a question about associative arrays.

    Cheers

    Anyone have an answer for the hash table question?

    I agree I thought the exam overall was pretty good, only some issues with the questions already identified - MC Q6,13 SA Q4

    Thanks Mark.

    Had a quick look over the exam.
    I like Section C of the exam. Good questions.
    Multiple choice are pretty good too.

    My query though, is about Section B, Q 4.
    This regards Hash functions. However I could only find one, optional reference to hash tables in the Study Design. Elsewhere it refers to data structures as being ones that are relevant to the selected language.

    I've pasted the excerpt below... can anyone clarify whether when the Study Design say 'or', it actually means 'and' ?
    Hence my surprise that it was on the exam.

    Hi all

    Paula says there is no second paper, so the fur can start flying immediately.
