IMPORTANT INFORMATION FOR PRIVATE CANDIDATES
The registration for ‘A’ and ‘O’ Level exams as a private candidate usually opens around mid-April (Please check SEAB website) and closes before mid-May. If you are registering for a Science subject (Physics, Chemistry, Biology or Combined Sciences), at the time of registration, you will be asked whether you have done any science practical training in any school, centre, or institute. Thus you must begin your science practical training before April. Science practical training in Singapore Learner qualifies as practical training for the purpose of registration for Science subjects for the ‘A’ and ‘O’ level exams.
Thus if you are considering Singapore Learner as your science practical training provider, you must register with us and complete at least 4 basic practical sessions for each subject by 31st April for us to certify that you have attended science practical training. As students usually do about 10 practical sessions per subject to be competent in practicals, the rest of the lab sessions can be done from May to early October, including the prelim/mock practical exams.

Physics Practical – Period of a Pendulum
Conducted my first Physics Practical this year last Sunday – Finding the Period of a Simple Pendulum – for a S4 student who had not done any Physics Practical while in S3. Strange but true.
Although this is a simple physics practical, students can still make the following errors:
(1) Not measuring the length of the pendulum as the distance between the point of suspension and the middle of the bob;
(2) Not securing the string such that it can slip as the pendulum swings;
(3) Allowing the pendulum to swing in an oval or circular fashion (not in a single plane);
(4) Counting wrongly the number of oscillations;
(5) Not recording the data in the table to the correct number of significant figures;
(6) Choosing the wrong scale for the graph;
(7) Not drawing a best-fit line;
(8) Writing the wrong unit for the gradient;
Looking forward to the next Physics and Chemistry Practicals.

What to do if you are failing in Integrated Programme?
Throughout the years, be it from my personal experience in the Integrated Programme system, or from the many IP students under my wing and those who come for free consultations, I have encountered all the different types of IP students. But one problem still bugs me, and that problem is this:
If you are a student who is failing in the IP system, what should you do? Besides investing heavily in tuition, here are some steps you can take in order to troubleshoot your problems.
- Am I working hard enough? That is the most basic question you have to ask yourself. The IP system is meant to be more challenging. Putting in little effort in your studies is just shortchanging yourself. As an IP student, you need to develop the mentality of working harder and being more proactive in your studies. So for those of you who have been slacking off, work harder and don’t give up! You are in the IP system for a reason, with enough work you will catch up and pull through. Practice some delayed gratification, put aside your playthings and put in the work. You will be surprised at what you can do once you put in more effort.
- I worked hard but failed, and now I feel really bad, what should I do? First of all, working hard alone doesn’t guarantee success, especially if you have been going in the wrong direction. Seek help from your school teachers first! The IP teachers I know are very caring, and they do their best to help you if you were to meet them halfway. Schedule a consultation with your teachers in the library to clarify all your doubts. It is likely that you have a deep conceptual error in the subject that went unaddressed, or you cannot understand the objectives of the exam questions. Your teachers will be able to help you with those problems as they are the experts. With their guidance, you should be able to do well. Never be shy in asking questions, especially when you are struggling. Many students before you have struggled as well, but with the help of their teachers, they have done very well for themselves eventually. Don’t give up!
- I have worked hard, sought help from my teachers, and it doesn’t seem to be working, what do I do now? Usually, this problem occurs when a student has taken the wrong subject combination. Students can take a combination because they have more friends in the same class, only to realize they do not have the aptitude for the subject or have no interest in the subject. If that happens, seek advice from your teacher in order to change your subject combination to something that suits you more. It is a drastic change, but it is necessary if you have exhausted all means and do not see a way out. If you have taken too many subjects, you might want to consider dropping one as you cannot handle the workload. Additionally, if the level as a whole is not doing well in certain subjects due to a sudden increase difficulty, there will be steps taken in order to moderate the scores. As long as you show good effort and attitude, you will eventually pass.
- I don’t see the point of all of this system, and I had enough. What else is there to do? At this point as a student, you might feel helpless because you have encountered certain emotional problems, and are struggling in a competitive system. Please seek help from your school counselor and address your emotional issues. It is equally important to take care of your mental well being besides your studies. Having a healthy mindset will put you back on the right path to success.
Every year, there will be IP students who are failing, have failed/retained, or have stopped attending school altogether. This is a matter that is close to my heart, as I have had good friends who struggled through such tough times. But I have also seen them rise above the occasion and bounce back. If you require a consultation about your options, or maybe even just a listening ear, please Whatapps Admin Staff to schedule a free consultation at 88765498. Do not despair, keep your chin up, and I wish you all the best in your studies.

IP Y1-Y4 SCIENCE PRACTICALS
Study Tips: O-Level Physics Chapter 16- Static Electricity
| Key Ideas |
| 1. There are two types of electric charges: positive and negative charges.
2. Like charges repel, unlike charges attract. 3. Electric charge is measured in coulombs (C). 4. Electrostatic charging of insulators by friction involves a transfer of electrons. 5. Electrical insulators do not conduct electricity because they do not contain mobile charged particles. 6. Electrical conductors are able to conduct electricity because they contain mobile charged particles (electrons). 7. Electrical conductors can be charged by induction. 8. Electrical insulators that are charged can be neutralised (discharged) by heating or exposure to humid conditions. Electrical conductors that are charged can be neutralised by earthing. 9. During electrostatic charging and discharging, only electrons are transferred. 10. An electric field is a region in which an electric charge experiences an electric force. 11. The direction of the electric field is the direction of the force acting on a small positive charge placed in the field. 12. Some hazards of electrostatic charging are lightning, and electrostatic discharge near flammable substances. 13. Electrostatic charging is used in photocopiers, electrostatic precipitators to reduce air pollution, spray painting to produce an even coat of paint. |
IMPORTANT STUDY POINTS
| 1. | Be aware of the formula Q = nq to calculate the number (n) of charge carriers given the the charge (q) on one particle and the total amount of charge (Q). |
| 2. | As 1 C is a large amount of charge, must know how to use or convert units such as millicoulomb and microcoulomb. |
| 3. | Must know the difference between how insulators and conductors are charged, and how they are discharged, and be able to explain these processes only in terms of the transfer of electrons. |
| 4. | Must know the difference between what happens when an insulator touches a charged object and when a conductor touches a charged object. |
| 5. | Must know the correct sequence for producing two similarly charged conductors, two oppositely charged conductors and a single charged conductor. |
| 6. | Must be able to define electric field and draw electric field patterns. |
| 7. | Be able to describe the dangers of electrostatic charging. |
| 8. | Be able to describe how electrostatic charging is used in photocopiers, precipitators and spray painting. |
