It seems that since 2005, the Ministry of Education has stipulated to colleges and universities that make-up and re-examination fees cannot be charged for the initial examination, and the re-examination fee is generally 50~ 100 yuan per credit, except for art.

This is a passage about the decoration fee in the Notice on Doing a Good Job of Charging in Colleges and Universities in 2005 formulated by the Ministry of Education, the National Development and Reform Commission and the Ministry of Finance.

In 2005, the tuition and accommodation fees of institutions of higher learning remained stable, and should not be raised for any reason or in any form or disguised form. In addition to the fees prescribed by the state, no new fees may be introduced around the country, and schools may not charge students any other fees other than those prescribed by the state, such as transfer fees, sponsorship fees, enrollment expansion fees, orientation fees, cross-regional construction fees, college entrance examination fees, holiday accommodation fees, make-up fees, revision fees, etc. Graduates who violate the agreement and fail to find employment in the agreed unit shall not be charged "liquidated damages" by the school; Students are not allowed to collect donations for any reason or in any name.
