2015 HSC Extention I Mathematics Predictions (1 Viewer)

So, what do you guys think? Will it be as easy as last years? What topics will compromise of the last section? Projectile? Rates of change? 3d trig?

 

[petergriffin198]

In my opinion there will be a hard projectile and medium binomial expansion for Q 14

Binomial theorem was easy last year. Let x=-1.

Year before? UGH.

So this year will be interesting.
_____________________________________
Projectile motion was solid. Expecting same difficulty this year if not slightly bumped up.
_____________________________________
Parametrics was so annoying. I felt so stupid when I saw the answers and I realised I missed the simple concept of m=y/x. But apparently that wasn't just me.

So, depending on how you look at it, the parametrics question was 'hard' last year.
_____________________________________
3D trig, hasn't been around for a bit.

Note that they will try not to make the questions in two consecutive years similar.

Probably be harder since last year's was pretty easy comparing to other years. I feel they will have a 'traditional' binomial theorem/probability, projectile motion and a question that will incorporate a few topics for Q 14.

The bulk of last year's Extension 1 exam was definitely easy. I found 2013 much harder than 2014. But, unfortunately I was having a really bad day and I only got 94 as an aligned mark doing the 2014 paper. :/

Should've repeated. I just couldn't be bothered putting in the workload.

How about 3D trig involving Parameters and Related Rates.

feels when u lose 3 marks for this,

 

[turnerloos]

I reckon projectile or harder prob

Oh dear. I did that once in an in-class test and that was humiliating enough.

Yes, I noticed it.

Whoever wrote that should go on detension.

3 marks? Was the marking criteria only like 'marks for correct solution.'?

 

[iforgotmyname]

I think this year will feature a hard binomials which will make everyone shit their pants. Hopefully not 3d trig cause 3d trig is cray cray sometimes

I just finished 4u and my friends and I were pissed at the lack of circle geo and induction in the paper, so it could be in 3u to make up for it (something i'd like tbh)
