Let me ease your fears. You have already submitted your application form and there is nothing further you can do. Learn to grow up and be responsible for your actions. Do not blame anyone for your mistakes. Whether you are successful or not, learn to accept rejection too.
Life is made up of successes and failures.
Be prepared to win and sometimes to lose and take it gracefully. If you are not given the university of your choice There are only seven universities and all are funded and backed by the Malaysian government. Do not assess a university because of its name and reputation. New universities may strike harder to provide better quality education and facilities. Ultimately it is the students performance that counts.
