Cooperation in the implementation of Integrated AB & C Brevet classes with campuses or other educational institutions. This program is run with the aim of prospective participants more easily determine the location of the class in accordance with the place of residence. The partnership that was built was very optimistic by seeing the HR needs of taxation in the industry continue to increase. Teachers' management, syllabus, schedules, and Brevet modules that TaxSys had prepared made this collaboration easier to implement.
