Here is my situation: I am currently a physician now for the last 20 years. I'm 51. I have a B.A. in Astronomy which is my passion. I want to go back to graduate studies in physics/astronomy. I tested this out several years back and took a graduate astronomy course at our local university. I was passing the course but realized that this is something I cannot do part time. So my plan is to review the physics and math over the next couple of years and then take the GRE physics subject test. Suppose I kill that test and do extremely well on it. Is there any chance a program would take me seriously? Have any of you had any classmates like myself? I would be very interested to know what you think.
