Doctor and Dentist are the high paying jobs in your list, and you don't need much math for those.
My kid in the UK went that route, Chemistry, Biology, Math, English Lit were what she required.
The university was more interested in a broad education than math skills (hence the English Lit).
Physicist. Chemist, Engineer, scientist would be lucky to earn 25kbht/month in Thailand. Better off studying Political Science to get a government job.
Why make the effort only to be able to get a low paid job?
