Goodbye Methods score, goodbye Methods scaling, fml

[sisyphus]

I only got about 70%, what grade would that be?

[BLACKCATT]

someone please help me!!
If ive lost 20 marks are my chances for 35 raw a zero?

It depends on your exam 1 and SACS as well.. And how the rest of the state goes.

Today, we must all commemorate the efforts of one very average student. This student, namely me, has risen to the likes of Jesus in terms of their guessing ability, for out of the 10 MC questions guessed, 9 were guessed correctly.

In other news, I didn't use -10 in the T-Jones related rates question. Any penalties for this or would they let it slip?

but everyone seems to have done really well
and people are saying the cut off for A+ will be higher, so ultimately my chances are pretty low right?

[Aman476]

I've lost 4 marks at best 6 at worst , that plus two marks lost yesterday there goes 46/47 raw haha fk

[Fick]

are my chances for a 35 raw gone if ive lost 20 marks??

no way. if you got 32-35/40 in exam 1 then you are looking at 38+

Hey just a heads up that there are some errors in the solutions I posted: they're listed in the separate thread

For the question where you had to find the 2 tangents, I found the required p values and then subbed them in to find the y values. Wrote the co-ordinates out instead of finding the equations. How many marks lost?

Q21 seems to be one that was commonly found difficult - I got D for it.

A = area of two triangles + area of rectangle (if you split it up)
= pcos(x)psin(x) + p^2sin(x)
= p^2(sin(x)+cos(x) + sin(x))

If you graph y = sin(x)cos(x) + sin(x) you'll find there's one local maximum. Work out stationary point, x = pi/3.
