Na it wasn't. ill try and explain it but just say you use the value of $10. a 30% discount from $10 is $3 discount. so $10-$3 = $7 now a further 20% discount is applied so 20% of 7 is $1.4. so 7$ - $1.4 =$5.6. so the total value is $5.60. now if you take $5.6 from the original value of $10: $10 - $5.6 = $4.4. so meaning the total discount from $10 was $4.4 = 44%. hopefully you can understand that

Nesa spared us for not writing many network and probability questions. I think the exam was just right, at separating Band 5 and 6 students.
My mind was doing backflips reading the temperature graph question, but I managed to get the hang of it.

The multiple choice went decently. Although, I should've read the formula sheet during reading time, realising the upper and lower bound formulas were in it within the last minute of the exam.

Despite it all, congrats for completing the exam everyone!!

Just double check Q29 (a). Should be total amount repaid, not just one monthly repayment.
