TOEFL study

I will take TOEFL exam on Dec. 12th. I should take it. Unitec university required me 550 points, but my best score is 510 points. I need more 40 points. I have to study more and read English more for Section 3. I study 0.5 hours everyday now. It is not enough. I know that, but I don't have much time to study. I will go New Zealand January 27th, so from now to that day, I study English harder than now. I really regret why I didn't study English. It is no use, so I really work harder from now. (109 words)
