With the increasing number and scale of students, in order to provide better teaching services for students, the company set up a teaching research group at the end of 2006, which is responsible for the research of computer grade examination, teaching organization and teaching effect, data collation and so on. With the support of all teachers and students, the teaching and research group has achieved many research results after long-term research. Independently compiled and published more than 20 sets of internal materials such as the second-level C language and the third-level network technology professional teaching materials for the national computer rank examination training, and developed several versions of the national computer rank examination computer simulation system. At the beginning of 2009, the second-level C language training class and the third-level network technology training class organized by the company were included in the national "Eleventh Five-Year Plan" teaching materials. Every year, a large number of test questions hit the textbooks and internal materials used by students, among which the hit rate of computer test questions is over 95% and the hit rate of written test questions is over 80%.
