Alright LGBT. I need your help and opinions?

i suggest you do go along with philosophy. as a math teacher in highschool, yuo can already cover mroe than one subject. for example, if you can teach calculus, you can also teach pre-calculus, algebra 2, etc.... it's all the real same. the only reason you would need to be certified in another subject would be if you taught something specific, say chemistry, then you would probably need to be certified to teach something else.
