Of course. Official website of Jilin Institute of Chemical Technology shows that the topic of graduation thesis can be changed halfway. The premise of changing the topic of graduation thesis is that it must be reviewed and agreed by the graduation thesis supervisor and wait for the teacher's notice. The teacher will examine your re-selected topic to see if it meets the requirements of your graduation thesis. It's not just users who say that they will change, but they should do it in strict accordance with the regulations of the school and the guidance of teachers.
