[Year 12 SofDev] 2017 Software Dev Examination Report is out

Tue Jun 5 00:14:29 EDT 2018

Hi Chris,

Thanks for the response, I find this confusing.  I would think the testing table should be based on the written component not on the pseudocode that already has errors in it.  If you go on the written part of the question, they need to have either enough money or have given permission to top up, the key being OR.  The pseudocode has the error of AND, so are the students supposed to create a testing table from faulty pseudocode?  I would think the testing table is developed from the written component, so you then find the errors to answer 8b.

Test No.

account_balance

topup

Excpected Result

Actual Result

4

5
(=5)

False

valid_booking = True
No message

valid_booking = False
Low balance message

The True in light blue above is actually False in the examiners report, which I think is incorrect.  If you have the money to pay the fare then surely it's a valid booking.

Neil.

Hi Neil,

There are two problems with the algorithm described in the pseudocode.
Firstly, it requires top-up to be true, regardless of whether there is enough money to pay for the fare.
Secondly, it requires that the balance must be greater than $5, not greater than or equal to.

Regards,

Chris

Can someone take a look at Question 8a in Section C, and either enlighten me or confirm the error.  In test 4 the account balance is 5 and topup False, I would expect the result to be "valid_booking = True", as there is enough money in the account to pay for the ticket.

Look forward to the replies.

Neil.

Multiple choice Q10 was marked as ambiguous. That's great and all but what about critical path question? You know that concept that wasn't examinable that was in the exam...

The list has been pretty quiet about this (there's usually some robust and healthy discussion around it) but I just noticed that the Examination Report is out on the VCAA website.
