How did you find the exam? Share your thoughts here

It was actually a pretty good test thankfully; but i over studied. I swear if i didnt study, i'd put the same answers. But yeah. IT WAS SO FREAKING GENERAL !!

 

[zombies]

Easy! Although on that very last section it took me a while to figure out the last question on the trig bit and the last two questions on the triangles... And then I got them and I was like durrr lol cos it was actually really easy.. Felt a bit stupid =P

 

[RealiseNothing]

Pretty sure I got 100.

 

[Lina3]

It wasn't hard but the test was rather long so there was more room to make silly mistakes.

 

[Laeth01]

I found the first 10 or so questions quite easy actually... but as the paper progressed i felt like crying

for i think it was Q52 they asked to write a Expression, i drew a sad face and wrote some numbers lol

 

[falsenthusiasm]

Pretty sure I got 100.

Me too. But I'll just say I'm also pretty sure I must have made a stupid mistake somewhere.

I thought it wasn't hard ... I did it twice and still had half an hour left over for Section 2 ...

I believe it was

t = 4s - 2

I think it was easier than expected, but i had no idea how to do the last question non-calc.
i substituted and ended up with a retarded number.

can someone explain it ?
the a*b = 1 - a/b

i think i took the most time on that stupid parabola question, it was so simple yet i found the vertex and axes of symmetry and everything LOL.
I felt stupid afterwards.

Worst case: 80
best case: 95

 

[Laeth01]

i wrote some 15 x 7 = 105 / bla bla bla lol might get something for aimless working out? >.>

2*(3*4)

basically, 3*4) = 1 - (3/4) = 1/4

2*0.25 = 1 - (2/0.25) = 1-8 = -7

damnnit !
i got -5 !
what the hell !

 

[jadenmaccas]

Easiest exam ever!! Finished with an hour to spare :O
But I might have done something stupid hope it goes well!

 

[tarasomerville]

I believe it was

t = 4s - 2

That's right

Anyone else start with the short responses in section 2 (when we got it) rather than MC? I've just started doing that (in every exam) thanks to my math teacher's advice. It takes so much stress away when you finish them and realise how much time you have left for MC Rather than starting with MC and trying to write last minute.

I must say... I think this was the best exam! I think I topped it! Well, at least, I felt most confident in this exam than the others. For a math exam I was surprised at how easy it was. Also I only guessed about 4 MC and 4 box responses YAY

2*0.25 = 1 - (2/0.25) = 1-8 = -7

lol I got 7.333 for some reason
Oh well

can anyone confirm???

 

[CrackerMo]

Quite confident about a 100. Good thing i didn't waste time studying for it, it was so basic =="

 

[Deliriously]

i got 2.2~~km/h (cant remember) for the increase in speed :/
