Go to http://www.jpa.gov.my/2009/03/1030/lang/en/ to apply for JPA/MARA scholarship. You may also want to check out malaysia-scholarship.net for Malaysian scholarships.
As for myself, I'm only applying for MARA scholarship, because MARA rocks! I applied for Medicine. I must admit I hesitated before clicking that choice. Good luck to all of you!
