Can someone explain Q13 in the core? I got D... rise over run gave me roughly 0.4 which is closest to 0.2?
Also Q4 in Geometry and trig I got D? The horizontal distance between A and B.. I'm just not completely certain...
If anyone could bring me some clarity that would be much appreciated!!

Anyone aware of how many marks you can drop across both exams and still get 45 or above?

ive dropped 3 on exam 1, but 2 of them was mis reading the question. If i get 60/60 on exam 2 what will i be looking at, if anyones aware?
Im on 98/100 on sacs near the top rank and in a extremely strong cohort

General rule for a 45-50 is one mark lost is one study score.
It doesn't matter how you dropped them, if you dropped three then you're looking at around a 47/48 if you ace exam 2.

The lower and upper medians give the gradient, they had the same y value, therefore a gradient of 0. Double check your median points?

As for trig, the angle of depression was 23, therefore the interior angle of the triangle connecting a and b, is 67 degrees (90-23). So you use tan(67)=horizontal dist/150

I have a question regarding Q9 of Core -

I did the equation and got -0.005, however, surely fuel consumption plotted against the weight of a car would be a positive slope?
E.g. wouldn't fuel consumption go up as the car for heavier and vice versa?
Thus, I gave D as the answer instead of B... what do you guys think?

Note that it says fuel consumption, in km per litre of fuel. So a car that weights more would travel less km with one litre of fuel.

I got 36/40 on the first exam, I am ranked top 20  and on 94% sac avg in a very strong cohort,
if i get 56-59/60 on the second exam what SS am i likely to get?

Top 20 is very vague, what was your sac average?

[Dan1995]

94% sac avg full marked everyone but trig which i completely screwed.

56/60 would be about a 42-44, depending on cohort strength and overall state performance.

Yea, it'd travel less km but consume more fuel per km, hence fuel consumption...

any way to boost my mood, did so many practice exams and only got 37/40. All three were the stupidest mistakes. Rank 2 in a extremely strong cohort, acing exam 2 is there any chance of a 48?

48 is still a chance, especially in a strong cohort.

Good luck for Exam 2 everyone!
Just aim to kill it, don't worry about what study score you'll get if you drop x number of marks. Give it your all and make sure you come out happy with yourself and how you approached the exam!
