Since the implementation of the college entrance examination, candidates' college entrance examination scores and the actual admission scores of colleges and universities in previous years have become an important basis for the college entrance examination to fill in volunteers. However, due to the different difficulty of the exam questions in the college entrance examination every year, the number of candidates taking the exam is also different.
Main advantages:
In the past, most people often relied on estimates, such as how much higher the admission score of a university in previous years was than the control score of that year, and how much higher their own score was than the provincial control line. Compare the two values with each other to interpret the college admission data over the years. This method is very simple, but the feeling component is too big, just compressing the score area.
