I'm not sure if this is the rights place to ask this question. If not, please direct me to the right forum section. Background: I'm 38 yrs. old and am considering a career change. I have a bachelors in physiology and a masters in medical science. I have been working in medicine since. However, I think physics (astrophysics/astronomy?) may be what I'd really like to be doing. Even in undergrad., I had a strong interest in physics - just didn't think it was the right career at the time. Now, I am heavily considering pursuing it, but I need to get some more information. Aside from more physics career research, I 'm trying to figure out how it could be done logistically. While I had 2 quarters of calc. and 1 yr of gen. physics, it was long ago and would probably need to retake those classes. Other than starting completely over as an undergrad (which is a little difficult as I work fulltime and can't quite finnacially swing being a fulltime student), how best could I purse this? I can take all the undergrad. math courses online, but actual physic courses would need to be done in a class/lab setting Would I need a bachelors in physics to get into grad. school? What undergrad. courses would I need to take for grad. school? Any recommendations, readings, resources are appreciated.
