MOCK EXAMS FOR SCIENCE PRACTICAL

END OF PAPER

Note: The above answers had been hurriedly worked out by Mr Teng, our H2 Math tutor.

——————————————————————————————-

Errata: question 7(iii)
This question is really confusing due to the word “before”. However, after much discussions, Mr Teng concludes that he is wrong. The answer should be n=12. If you put the emphasis on how many MUST be cut off, 12 will be the correct answer. If you’re my student, you will know that my English is terrible. Haha.

Question 6(iii)) should λ = 8μ/7.

Question 9(iii) due to the lousy app should be 24n.

Disclaimer: Question 3
The line y=1 was drawn as part of my solution to (ii). So long as the diagram is clearly labeled, there should be no issues.

Any more issues, please let me know. Lastly, big thank-you to all the j1 and j2s who helped me clarify and explain the English behind the statement. And do watch out this space for P2!

(3) Beware the critical years in math education …

A. Math

Reflections on my Sec 3 A. Math Headstart class today …

Posted on November 11, 2013 by admin

I was quite happy that three students turned up, knowing well that this is a ‘holiday’ period for them. I began with one of the easiest topics in Additional Math, Simultaneous Equations. The difference between Simultaneous Equations in E. Math and in A. Math is that in the latter, one of the given equations is non-linear.

Both the Elimination and Substitution methods can be used, but the latter is more popular. After teaching for half an hour, I gave them a worksheet to do, and selected 6 important questions for them to complete. But two of them were stuck at the first question and all three couldn’t complete the second question without my help. This was surprising because all three did quite well in their recent SA2 Math exam.

Their main problem was that they had forgotten some of their algebraic skills, such as in handling algebraic fractions and factorisation. Imagine not doing anything now about their math and starting to learn this ‘simple’ topic in Jan 2014. It is then easy to see why many students do badly in A. Math and in the pure sciences in secondary three. Sec 3 teachers teach at a fast pace and before students are ready, they move on to the next topic. I’m glad that some students and parents see the importance of attending headstart classes in Pure Math and Pure Science; it is not about being ultra-competitive; it is about survival.

PRI 3 – PRI 6 CONCEPTUAL LEARNING SCHEDULE 2014

Posted on November 10, 2013November 13, 2013 by admin

Classes marked with a ‘*’ are Conceptual Mastery courses whereas those without a ‘*’ are Conceptual Drilling classes.

Conceptual Drilling classes are for students who need to strengthen their maths or science foundation, using constructivist and scaffolding approaches. Conceptual Mastery courses are for students who are ready to learn how to answer or solve challenging questions, using a metacognitive approach.
