Yo katie, I got 8 as the answer for the critical path question part c, I don't remember my working out for it but I remember I got 8 for it. Can you explain how you got 9?

so you’re right, those two edges added up would have to have a weight of 8. HOWEVER, the question isn’t asking for the weight of the two edges, it’s asking how much time IN TOTAL can occur between them. this means that the time can include float time - for example, after F is completed, H can be delayed by an hour. this would mean that the total time that has occurred between the start of F and the end of H is actually 9 hours, not 8. i hope i explained that properly

Here are my solutions to this years exam! I know there have been other solutions but there have been wrong answers in them, so I was told to make my own set. Let me know if I have any errors in it as well!

this might be a dumb question but for question 15 (multiple choice) why is the answer D? (i chose C)

IQR of D is smaller than the rest, the others have the same IQR, therefore D has a smaller IQR which means that it is not representative of the box plot.

no it’s all good! there was a lot of discussion around that. so basically what you had to do was create a five number summary from the data. after doing that you’ll find that they’re all the same except for D.

that’s alright! i get it, i guessed C and only realised what i had to do in the last 20 minutes.

 

[MoeyNeeds90+]

maybe insufferable isnt the right word idk

mate you just need to stfu

 

[Morninfofhello]

that’s alright! i’m sure you did great! if i remember what i did fully, i think i got 98 raw. i think.

Slay girl good on u, good luck on the rest

Im raw-ing 98 right now as well, the only mistakes being MCQs (face palm), do you think we'll manage to SR?

no way the hsc expected us to do this working out for one mark

slayyyy, am actually confused how they get our final hsc mark for the subject, cuz dont they consider internals too? (i think i did better in internals than the hsc so)

ikr, i barely finished the paper in time
