Frankly, i don't really like Malay because i think it is a very confusing language.(they somehow always add need vocab or even change the grammar rules etc..this is my opinion)
i think Bahasa Melayu should combine with Bahasa Indonesia....so that both country can understand each other well...but that's impossible....haha
by the way , i can speak casual Malay to Malay people....and i think the written Malay that u all learn in school is different when talking to Malay people because they use their own casual Malay slang....that's why some chinese people talk in bahasa baku....it sounds so weird to Malay people...hehe
i usually speak in Malay to those cashiers and security guards so they can easily understand wat i'm talking....if not sure when "san fu" when talking to them.
until now Bahasa Melayu is still a compulsory subject in all schools....but i still think everyone must learn it but dont really need to master it ....coz when u're coming out to work in the society especially the business/IT/Accounting/Marketing field....English is a must! and that's why these college (no idea about Univeristy) courses almost all are in english.
Just get a PASS in Bahasa Melayu in SPM will do! all the best...
