The Journey has just begun

Parents & Students,

Hope that the dusts from the uproar of the PSLE 2009 Maths, Science & Chinese paper have settled somewhat by now.

With all the media coverage and netizens voicing out, I'm sure the relevant authorities are hearing us loud & clear. And we do hope that they will listen and review.

Well, with the passing of one major phase of the lives of our children, it would be wise to prepare them for Secondary School.

My daughter got into Secondary 1 last year, and the increased in the number of subjects, and the expectation for them to do a lot more self studies by themselves, makes the switch not so easy.

Therefore, prepare them mentally so that they are able to mix well with new classmates and settle in new environment quickly.

We send our kids for Financial Literacy workshops then, and they learn to seize opportunities, speak out for themselves, budgets their own pocket money, negotiate with us for time for studies, computer & watching TV, and more.

Don't just lament over the PSLE papers, many students are affected by the difficulty level, only those who are able to do more of these questions qualify to get A*.

Do let your children know that "The journey of Life" is more important than just the end results. And journey with them, and learn things together, it's much more interesting this way.

So all the best to all of your kids.
