Joining the airforce!

Hi everyone, I just decided recently that I am going to join the airforce in May 2020, and honestly I don’t know too much about it.... I will need to go see a recruiter soon probably (a little nervous to do so since I’ve never done anything like this) I was wondering if any of you could give me advice as to well all the tests I have to do to get in, I know I have to be able to do a lot of physical stuff so I was going to start working on that until May... I already work out but not like push-ups and running more or less like my legs and arms and maybe a little cardio so I will be switching it up for that, and as well as the like actual tests? I don’t know what they are but I’m sure there’s math and I suck at math. I only went to 9th grade in high school, and eventually got my ged. I have taken a couple college classes as well. And what is training like? Thanks for any advice!
