I am glad the government had made decision to use Malay language for Math and science subjects. Now I can sing with my kids the 'sefer' song "Dua kali Dua Empat .....".
I could not understand who made the recommendation to use English earlier.
I did all my math and science at primary level in Malay language and never had problem during the university time and in fact most of the time I did better that those English students from UK. One of my friend who completed his study in Seoul University, Korea also did very well in his study.
Both of us had done many iconic projects initiated by Dr Mahathir and he should be proud that the language our engineers learned during their chilhood days were Malay not English.
