Teacher qualification certificate. What does it mean to be qualified as a teacher with the same or similar major? I study rocks and soil. Is it suitable for studying mathematics or physics?

It means that you must hold a teacher qualification certificate, majoring in mathematics or physics at the university.

First of all, it depends on what subjects are on your teacher qualification certificate. If you want to be a junior high school math or physics teacher, you must have a senior high school math or physics teacher qualification certificate (you can also teach junior high school) or a junior high school teacher qualification certificate (you can't teach senior high school).

Second, the geotechnical major has nothing to do with mathematics or physics, so your major is not suitable for these two subjects.

Third, for your major, you can consult the local education department to see which subject position you can apply for.
