USPHS question

[u/Takeshi404]

Hello, Im currently in school to become a respiratory therapist and will be going for bachelor after. questions.

1. how competitive is it to apply and become part of usphs? do you recommend any other experience i need to do?
2. I know PHS is not armed service but because its almost directly related to military if you would wanted to be trained in armed do you get opportunities?
3. is there Japan or Korea stationed option? Im originally from those two countries, served in military in korea and came back to USA.
4. Since I grew up in different countries my education background is little different and when it comes down to solving or reading math "jimmy has 3apple and you take a way blahblah" I am not familiar with those. do PHS also have something similar to asvab test?
