SM Exam 2 2009 Suggested Solutions.

reckon 72/80 will scrape in for a low A+?

Yeah most likely.

[angelboykevin]

what about 67\80? low A?

High A.

hey, don't you need to label the two asymptotes in 4b?

Well in most exams I've done they say label x intercepts, y intercepts, equations of asymptotes etc.

However the question only said "clearly showing the location of the x intercepts" so asymptotes aren't really required, and since the graph is restricted, I think you only need to show what the graph looks like.

Putting in asymptotes won't be wrong but I just don't think it's necessary from experience.

High A.

i got 36/40 for exam 1 and 67/80 for exam 2,, what do u think my enter will be roughly/ thanks alot bro

[dav132]

ah k, kewl.
thanks for the solutions
i don't think i went so bad now.
I didn't get an A+, but hopefully no lower than a B+/low A.

I ended up with 76/80, can't fucking believe what I did for that question in the area of complex plane part. I worked out the side length of the outer circle then subtracted that of the inner circle. I didn't work out the distance the car and bike travelled and I also screwed up the differential equation MC question. Annoyed that I lost 3 very careless mistakes, but if you had of offered me 76/80 at the start of the year, I don't think I would of complained.

High A.

Uhhh...I don't know how that assumption can be made, it could be an A+ going by 2006 and 2008...wasn't this exam harder than 06? Also 07 was 67.5 so yeah

Good work TT!

Yeah I felt similarly stupid when I realised what I did for the area question, completely misquoted the formula for area of a sector of a circle. 76 is a great score though.

[gilla]

what sort of study score would 76/80 and 38-39/40 get for specialist?

[TrueTears]

46+

[gilla]

are u sure TT, lol, i dont wna get my hopes up u know.

PS: i love your work

[TonyZ]

how many marks am i going to lose if i forgot to calculate the distance that the car and bike travelled...
