GCE A Level 2011 Oct/Nov H2 Maths 9740 Paper 2 & H1 Maths 8864 Paper 1 Suggested Answers & Solutions

(29)
Posted at 10:32 pm by Mr Loi in Mr Loi the A Level Tutor

Hello it’s me again *rubs eyes*

It’s been a looooooong day. And yeah the A Level Maths papers have been a little tricky this year.

While I recognize that many of have had a tough time working out the papers for the past two mornings, do spare a thought for me who have been forced by my sis to working out three A Level Maths papers in the past two days (plus tuition time) as you browse through my suggested answers to today’s H2 Maths Paper 2 which you may access here by clicking the Like button (if you haven’t yet done so).

Latest version:

H2 Maths Paper 2

  • 1.1:
    Q2(ii) Modified rejection reason to 2x < n (as kindly pointed out by Chen Jing)
    Q3(iii): x = -0.4847 instead of -0.4877 (misread due to pen no ink :P )
    Q8(iv): 13.5 – corrected rounding error (as kindly pointed out by Ah Wei)
    Q12(iii) – removed lower limit of 0 since there’s nothing stopping the number of people joining the queue to be greater than the number leaving the queue (as pointed out by sam)
  • 1.2:
    Q2(ii) – Simplified the final answer further.
    Q8(i) – Removed extra point from scatter diagram which should contain only 5 points (I swear I plotted only 5 points that night!!!)
    Q12(iii) – removed the continuity correction since the approximated aggregated Normal distribution is already continuous. Therefore no continuity correction is needed (apologies for this oversight and I hope this will bring closure to this part).
    Q12(iv) – added missing answer (too tired that night and missed this!)

As usual, please leave a comment should you spot any mistake in this set of suggested solutions – as mentioned it’s been rather tiring doing the many, many A Level Maths papers these two days *faints*

Last but not least, if you haven’t yet done so, do say hi to me when you drop by in Facebook ;)

Hello again everyone,

After having taken possession a certain booklet, I’m sitting in my sister’s car, looking up at the bright blue morning sky, while sending out this series of codes:

Q1-10 CCBCB AACCB
Q11-20 DCBDB CBADA
Q21-30 ACABC BCBAB
Q31-40 DCBDA BDDAD

Note: Answer for Q33 has been changed to B. Sorry for the misinformation! :(

Do they tally with yours?

Update: The list of workings and explanations for each of the answers (where applicable) have been compiled (along with the questions at the end)!

You may access here by clicking the Like button (if you haven’t yet done so).

Latest version: 1.1: Q38 – corrected typo and updated explanation

Hopefully this will help in some way to settle some of the debates regarding some of the answers (and hopefully not create more in the process!)

Good luck for those of you with your remaining Science MCQ papers! ALMOST THERE!!!

Hello it’s me again.

Something landed on my lap this afternoon, followed by what I could almost hear was a thousand screams of anguish coming at the end of today’s H2 Maths Paper 1.

To find out what happened, I’ve worked out my own suggested answers which you may access here by clicking the Like button (if you haven’t yet done so).

Latest version:

  • 1.1: Added the constant of integration (+c) to the answer for Q8(i) -thanks clarionx!

As usual, please leave a comment should you spot any mistake in this set of suggested solutions, which was produced under the peering eyes of some students from today’s class *sweats*

Oh by the way, do say hi to me when you drop by in Facebook ;)

Now go revise your

  • Functions (composite & inverse)
  • Transformation / Hyperbolas / Curve sketching (oblique asymptotes) (remember to use Radian mode should you be called to sketch a trigo graph!)
  • Integration by parts/substitution/ Volume of revolutions
  • Recurrence / Sequences (Tn = Sn − Sn−1)
  • Complex Numbers (Rationalization & Simultaneous Equations)

All the best for your Paper 2 on a very auspicious (I hope) 11-11-11!

がんばって!!!

Hello?

Hi, this is Miss Loi …

OH MISS LOI!!!

I’ve been waiting a looooong time for your call! You know har … my this son har … I dunno what to do with his maths anymore!

AIYOOOOOOH … headache arhhhh!!! …

To those on the Wait List aka 名册

The 2012 Temple Wait List
The 2012 Temple Wait List aka 名册

Miss Loi is currently in the middle of her annual phone call marathon to get in touch with all on her wait list and lending her ear to the nth+1 tragic 凄凉 academic tale.

As things stand, Miss Loi is almost done calling everyone on her wait list (*except for parents of 2012 Sec One students – see below).

If you have contacted Miss Loi earlier (via SMS, missed call, email etc.) but have only experienced a long eerie silence till then, Miss Loi is terribly sorry about this and would gently request that you call her again asap (Tel: 9380 5290) (sorry there are many on the list plus lotsa missed calls on both ends).

*Note: All parents of post-PSLE students will be contacted after the release of the PSLE results on 24 November 2011. *teng teng teng teng*

Meanwhile, GOOD LUCK to all A-Level students in your remaining papers – Freedom Is Near FREEDOM IS HERE!!!

がんばって!!!

Hello everyone and sorry that I haven’t been online for awhile (and that’s a looong while …)

Anyway, my sister told me to use her ‘plane‘ to ‘airdrop’ some Science solutions (another one of her funny ideas again -_-) but someone has apparently took off with it and dropped the following:

Latest version:

  • Physics 5058 1.1: Q2(a): Added “but the total amount remains constant” to the statement for the principle of conservation of energy. Minus 1 mark if that’s left out!
  • Chemistry 5072 1.1: Q2(d): Corrected “… chlorine gas will be produced at the cathode …” to cathode as kindly pointed out by this student. Thanks!
