What MC questions confused you?

For me, the very first question. (I didn't know what an Gantt chart was).

Also, the question about string/int/real sorting. I couldn't remember if "." and "-" came before the numbers in ASCII, so just guessed "String".

Pretty sure the sorts question was Bubble and Selection (starting from the right).

I found multi choice the hardest part of the exam.

First one was interview to find requirements.

I wasn't sure on q19, except that I put integer and real as I'm not quite sure how to sort strings.

I got a lot of Ds as my answers, and began contradicting myself.

Anyone know the exact wording of the string/int/real sorting question? Cause I cannot remember that question. :(

Don't remember but wasn't it just an array with the -ve number, a decimal and some other two numbers
If it's the question I'm thinking of then I think I skipped over the part where it said sorted. I thought it was asking what the data type of the array was. Oops. :(

That is what it asked for, I think I put string or something, either way I put only 1 data type, I was thinking the type(s) was a trick. I'm not sure whether arrays could be multiple types :/

Arrays can definitely have multiple types. It's vectors that are all of the same type (vectors are not in HSC syllabus).

Oh man, I put real down cause like you said arrays can't have multiple types. But now that I think about it, string could work too.

It's certainly not real, because the arrays are sorted and if it was all reals it'd be properly sorted.

I did 'Strings' but it could have been Strings with other types.
