vì là bài Thi quốc gia không phải essay trong IELTS nên tất nhiên không thể đòi hỏi nhiều. Nhưng trong bài viết bạn nên dùng nhiều từ đồng nghĩa ( synonyms) hơn.
Learning English every day probably change( increase) your exam mark( không sai nhưng nên dùng English test scores) because of popularity of english nowadays and we need to learn english as quickly as possible. First of all, to change(improve) the exam grades, you must try harder to get the better scores. Secondly, your knowledge standard will increase soon, as you gain knowledge by your own way, and you look up words by yourself. Thirdly, you can inspire by listen to music with lyrics or watch american, english film with subtitle, yet you could improve much much more your english words source than before with listening, also speaking skill. Furthermore, from my point of view, there is one way to study english, it can improve(enhanced) your grammar though, or your vocabulary by this method, named: "bath language". In conclusion, no matter who you are, what language you speak. Your native language IS good, probably practising english much easier, so that obviously you change your own mark easier.
