Two B-level books of Shanxi Datong University, literature and history 509, science and engineering 5 13, have low admission scores at present, and the reasons are not sufficient. The release date of the grade drop is August 5, 2009, provided that volunteers have filled in Shanxi Datong University, and the national candidates' liberal arts drop by 20, junior college drop by 40, art and sports drop by 45, our province's liberal arts drop by 30, junior college drop by 50 and art and sports drop by 60. Datong University loses points every year, and the range of which is different, high and low. If you don't accept it, I hope it can be solved again.
