    yes, you will lose a mark if you do not have it

    ALWAYS repeat the last pass, so you have two the same.

    You might know it is in order, but you need to do a final pass, so that the algorithm does.

    you should be fine with what you wrote, final (repeated) pass or a statement will do.

    Got everything right except wrote 2 12's instead of 1 and a 13 when doing my bubble sort, so will I just lose one for accuracy? And how will this affect the first fit decreasing 3 marker with this list?

    I calculated the lower bound fine at least.

    not sure, 60+ for an A.

    definitions are normally terribly answered, as will the dummy questions.

    I think the postie question will be a bloodbath too.

    LP was pretty kind.
