As a high-end original series in the gold test paper, the Hundred Schools Alliance Series is suitable for students with average or above grades. The cover colors of the four sets of papers are blue, green, yellow and red.
This series only comes out four times a year, which is incompatible with the temperament of the golden paper model worker. However, due to the high quality of these four issues, they were dubbed as "four famous auxiliary". These four questions are: pilot file, forecast file, guess file, and betting file. There are about 10 sets of papers in each issue, which are relatively few and easy to finish. From the name, we know that this series is based on originality and prediction, and does not involve simulation questions from all over the world.
