Hi tutor2001,

Surprising. What I understand from another parent ...under RP all Orange level topics will be covered + some simpler topics under Air levels.

[atutor2001]

Hi Dharma


All topics will be covered but not the TYS for orange level. Doing TYS is very important for Air & Orange level for most people though many smart kids there don’t need to anything and will still ace everything.

Doing TYS will expose a kid to all "standard difficult" question types and they can approach the question in the shortest way without going through the basic principles. That is how those that gone through the orange path will have an advantage.

However, IP also has its advantage - ability to think out of the box. IP students adapt better to solving questions that are "non-standard". An example is a question where the function is broken into different types for different ranges of x. Orange level students will face more difficulty for such question than the IPs.

Thanks atutor2001. Agreed that TYS is impt for major exams. Only a handful have the ability to do nothing much and still able to ace in everthing. Having said that, there are many who may just appear to be doing nothing much but go on to do very well.

PLEASE HELP:


Express 3969 as a product of its prime factors and give your answer in index notation.

3969 = 3 X 3 X 3 X 3 X 7 X 7 = 3^4 X 7^2

Vikaesh:

please explain to me what is an index notation and how the prime factors can be found out...

Hi mathsguru,


Need your help on this.

Daisy had twice as many pencils as Sulin at first. Then Rose gave 8 pencils to Sulin. After that, Rose had three times as many pencils as Sulin. If Daisy, Sulin and Rose had 134 pencils altogether, how many more pencils than Daisy did Rose have at first?

Many thanks.

Hi Kiasimom,

Here's my solution. To get started, try drawing 2 models representing Daisy and Sulin's pencils. Then, add on to Sulin's model by including the 8 pencils Rose gave her. From there, we can draw out Rose's model and solve accordingly.

I finally figured it out!! :celebrate:

What is


3a(2a - 1) - 2a(2 - 4a) = ? in the simplest form ? [please show step-by-step working...tks]

Hi Vikaesh,

3a(2a - 1) - 2a(2 - 4a)
= 3a x 2a - 3a x 1 - 2a x 2 + 2a x 4a
= 6a^2 - 3a - 4a + 8a^2
= 14a^2 - 7a
= 7a(2a-1)

I believe this is lower sec maths - algebraic expansion & factorisation.

Remember that: -ve • -ve = +ve. And \"simplest form\" usually requires u to factorise the expression to get the final answer.
