Last year's scores were: total score 230, writing 90.
The first two volumes were difficult last year, so the total score dropped.
The first two volumes of 307 are relatively simple, and the score line is: total score 255, writing 90.
This year's exam also depends on the results. The first two volumes are graded (close to the estimated passing or passing line, depending on the difficulty of the test paper), and the third volume is graded (estimated 90).
Hope useful to you
