Are there any mistakes in the following composition?
Our tutor Suki provides detailed comparisons between different years of English Language pastpaper, how the question structures are similar and what vocabulary are repeatedly examined, etc. I remembered she once said, "English Language is not only a test of your exam skills, but also a test of how determined and hardworking you are in finishing all years of its pastpaper." I took her advice and it paid off . Even though it is way past the time lessons end, she did not mind giving us extra time and bears each student's interest at heart.
