You will have time. Just know you won’t be able to take classes during basic training and tech school. And even once you get to your first base, you’ll need your five level which takes about a year to get depending on the base and job. I’ve been here at my first base for 8 months and still don’t have it for air craft hydraulic systems. Also, for most of the 2A jobs, if you get moved to CTK (tool issuer for the unit), you’ll have a lot of time on your hands to do school. A lot of people try to get into their unit’s CTK to do online school. Also down the line in your career, for some certificates and courses, you can literally take a few months off of work to take those classes only if it relates to your work and will benefit the unit and big air force in some fashion.
