First, you need to love English because if you never like English you will never able to score
Secondly, you need to check your grammar and always improve it by meeting with your teacher because the major reason why students in Malaysia cannot score in English is because they are weak in grammar
Third, listen to English music and try to understand the meaning of each word in the lyrics
Next, do more practice like doing essay and grammar practice and check it with your teacher
Last but not least, try to speak in English and have a conversation with your friends. Do not worry even it is broken English because it will build your confidence level...
Lastly, have a good relationship with your English teacher, ask for advices and always pray to ALLAH after you had put all of your effort
