1. After the results of the college entrance examination are announced, the corresponding rankings will also be announced. At this time, we will find a table of last year and the year before last as a query tool.
2. When we find the score corresponding to last year's ranking in last year's score table, we will know which universities this score can go to last year, so as to roughly locate the schools.
3. Then, according to the newly located university, float 10 points upwards and 20 points downwards, so as to screen out the schools that can go.
Use the same method to screen out schools like the year before last.
Finally, the colleges and universities that existed in this field last year and the year before last are listed, which shows that these schools are relatively stable and can give us great reference value this year.
