There are two aspects of this score —— "range" and "accuracy". This score is often misunderstood because many people believe that a high score is awarded if the candidate doesn't make any grammar mistakes. The score in this section is based on a number of different factors including:
1) Sentence formation;
2) Use of clauses(subordinate etc);
3) Use of complex structures;
4) Range of tense use;
5) Error density(the number of errors in each sentence);
6) The level of errors(whether the errors occur in basic or complex structures)
