a) she should go to university and go to career counseling thats what they do.
b) she could look online to see what kind of jobs are out there and what sounds interesting to her and what kind of education is needed for those jobs
Maths doesn’t always have to be an accountant.
Engineering, Architecture and alot of jobs in the design field require a good deal of maths and creativity.
If she wants something interesting and she’s organized, the organization and hard working could just mean she will progress in whatever field she chooses. She doesn’t have to choose her career based on those character traits.
Hope this helps 😉
