I am also studying as a kindergarten teacher.
It is more difficult to take the college entrance examination by yourself. I suggest you apply for correspondence courses in case you fail ~
If you change your major, I think you can also major in administration. If your major is good enough, you can also be a primary school music teacher.
To be honest, I don't really recommend you to change your major. Changing your major means you have to start over. If you continue to be a kindergarten teacher, you can get a kindergarten teacher qualification certificate during school, or you can actively get various certificates such as piano, vocal music and dance, and tutor your children after graduation. Of course, the exam compilation after graduation is very important! Preschool education is a good choice for girls! Steady!
This is my little idea, I hope it can help you ~
