不要担心,i am sure that your final score is higher than 250. if your essay score is 4,your final score is about 253-257.because your structure range is good enough, and there is only 6 distance.
What do you mean 'structure range is good enough', caz mine is 10-28 and total 190-250, is that good or bad? can i get 237 or more if my compsition is 4.0? thanks for your reply in advance!
