Registration for classes in 2018 has been opened. You can find out more about the class schedules here. Do note that JC1 class will commence in first week of January as there are registrations from IP students. For O’levels students, you can treat it like a head-start! We will also be holding a workshop for Post-O’levels Release of Results. So do stay tuned!
Prelims Exams was scary. H2 Mathematics isn’t that easy.
Students that had difficulties finishing their prelims exams, should consider working on their time management. The best way to do it, practice 3 hour paper… in a single sitting. And students should note to modify their TYS slightly as several questions in each paper are out of syllabus. In general, we give ourselves 1.5min for every 1 mark.
So here, I’ll share a list of questions that Mr. Wee has compiled. Mr. Wee also wrote e-books recently on solving non-routine problems. They are very interesting and provides the learners a new perspective to solving problems.
All the best for your revision!

Today I’ll share a question that came out of CJC Prelim 2017 Paper 1 for H2 Mathematics 9758. I think some of my student would have seen this question before and we discussed it in class before. Very technical question. This is question 11, I’ll share only the first part which is on the application of ratio theorem or mid point theorem. The second part is on application: Ray Tracing which I’ll discuss in class.
A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side. For the triangle show below, O, A and B are vertices, where O is the origin. and . The midpoints of OB, OA and AB are M, N and T respectively.
It is given that X is the point of intersection between the medians of triangle OAB from vertices A and B.
(i) Show that
(ii) Prove that X also lies on OT, the median of triangle OAB from vertex O.
Consider the mid point theorem and the ratio theorem first. Can be found in MF26.
Last year, I shared a handful of random interesting questions from the 2016 Prelims. Students feedback that they were quite helpful and gave them good exposure. I thought I share some that I’ve seen this year. I know, its a bit early for Prelims. But ACJC just had their paper 1. 🙂
This is from ACJC 2017 Prelims Paper 1 Question 7. And it is on complex numbers.
(a) Given that and , solve for and .
(b) Find the exact values of and , where such that
I’ll put the solutions up if I’m free.
Just FYI, you cannot complex numbers as they are not real…
This is a past year question that has been adapted from HCI. Pretty interesting topic… Let’s see how to unpack this question together… This question assumes that population problems (demographic issues are part of the natural process on earth, which would eventually balances itself over a long period of time). Government interference would merely make it worse, since their interventions are often “artificial” and would make matters already worse than what they should be. Moreover, governments are not able to always predict future trends and outcomes, hence it is advisable for them to leave everything to nature than by chance.
As illustrated by the Demographic Transition Model (DTM), population problems can indeed solve themselves without the need for government intervention. In stage 2 of the DTM, it is asserted that developing countries experience a decline in birth rates due to the introduction of contraceptives, induced abortions and a change in socioeconomic perceptions. As countries gradually industrialize from their original agrarian societies, rationalism overrides traditionalism, thus leading to a fall in birth rates as both men and women alike desire a higher standard of living. This involves having fewer children as they are expensive to raise, according to Caldwell’s Theory of Intergenerational Wealth Flows. This hence reduces overpopulation naturally without the need for governments to step in. The model also contends that high mortality rates eventually decline as well, due to the influx of medical technologies and increase in hygiene and nutrition standards. Thus, population problems gradually solve themselves in the long run due to the advent of industrialization and inevitable changes in societal perceptions and standard of living.
Nevertheless, even though the above mentioned model claims that populations stabilize naturally in the long run, this is in part due to measures and policies implemented by governments that are in line with national interests. In this case of China, overpopulation and a stress on national resources were narrowly averted due to the government’s legislation of the “one child policy” in 1979. The reduced strain on resources thus allowed the Chinese government to focus on stimulating economic growth and developing infrastructure to attract foreign direct investment. Another country with a similar goal in mind was Singapore with its “Stop at Two” policy from 1965 to 1984, which helped to solve population problems such as overcrowding and a lack of resources.
Government intervention also solves population problems such as population decline, which will be left unsolved if left to the masses. With a preference for smaller families and a general unwillingness to start a family in today’s modern society, negative or zero population growth often ensues. These have detrimental impact on affected countries, such as a fall in tax revenues, a smaller workforce and a high dependence of an aging population on the working population. As these socioeconomic perspectives are entrenched in the minds of young urban professionals, these population problems are incapable of eventually solving themselves. In this case, government intervention is beneficial. In developed countries like Italy and Spain, where fertility rates stand at a meagre 1.25, new generations are unable to replace past generations thus leading to population decline. The implementation of pro-natal policies could possibly help to increase the incentive for couples to procreate and boost total population numbers. Implemented measures include longer maternity and paternity leave in Switzerland, as well as cash incentives in Singapore. Another method of boosting population growth is through the relaxation of immigration policies, which allows for an influx of permanent residents.
Here are some reasons in tackling the demographic imbalance… What do u all think? But I would to raise some points… Many a time, the population policies done by the government are “hard to reverse” especially if they have been too successful.. An example would be Singapore’s Stop at Two policy. Even China has recently reversed its One child policy in hopes of dealing with the fast growing aging population and the male imbalance ratio.
But of course there are implications that come with these population policies… These would be for a discussion for another day.
P.s The above points have been contributed by an ex student from HCI. It has only been vetted and edited by the tutor.
Came across this question in class which stumps a lot of my students in answering this… It seems so contradictory right… to be humble in our modern day?
Ok let’s see what are some characteristics of our modern society first. We are driven by our pursuit of material goals, increasingly status conscious and technologically driven. So where does the value of humility fit in?
1) Humility allows us to lower ourselves and to examine our shortcomings. This virtue is especially important when it comes to dealing with business and in reflection to improve ourselves. In this modern world where it is very competitive, it is advisable for us to always examine our business but it should not hit the point of analysis paralysis.
2) We should dare to show and flaunt our wealth, status or even ability to others in order to stand out in this competitive world, otherwise how would people even recognize and take notice of us? If we do desire social status or even respect in society, the easiest and fastest way is to of course demonstrate our signs of success and flaunt wealth. Many have turned to that on social media seen from posts from #richkidsofinstagram etc. Besides such frivolous way of gaining respect, a more important reason would be for marketing needs. Marketing needs could refer to “selling” ourselves to companies in order to get that coveted job or to sell products and services to encourage consumers to purchase. One would need to “scream” in order to stand out for others to even take notice of us. Humility definitely has no value and place.
3) Humility could be expected from leaders as they are placed in a position to serve others and to demonstrate empathy. An arrogrant leader would be a definite turn off to most people as we definitely would not want our leaders to come from a moral high ground or to even impose their power, status and influence on us. Examples of such leaders would be Mother Theresa, Ghandi just to name a few. But we should take note that humility could also backfire, especially if one presents oneself to be too meek, it could be a sign of weakness and a lack of confidence. This could bring others to exploit the situation.
To what extent is humility really relevant in our modern society? It would be dependent on the context of the societies that we are in and what is the purpose we are utilising it for 🙂
