<p>Does anyone know a lot about astronomy PhD programs?</p>
<p>If so, I’m wondering if any programs don’t require extensive physics coursework. </p>
<p>If someone gets a good Physics GRE score even though he or she doesn’t have the physics coursework to back it up (i.e., he or she learned physics independently), is that a major problem for most programs?</p>
<p>Thanks.</p>
<p>Well, I’ve heard of people who get into totally unrelated fields than what they majored in. For example, a guy getting into a top PhD program in bio while having majored in history. The guy had a perfect GRE bio and math, or close to perfect.</p>
<p>Virtually all programs will want something like:</p>
<p>“credentials documenting prerequisite academic work that gives evidence of your ability to pursue a graduate program in astrophysics”</p>
<p>or:</p>
<p>"A Bachelor’s degree in physics, astronomy, or a related science is required. The GRE general test is required. The GRE subject test in physics is required. If the degree is not in physics, a strong physics minor is necessary. "</p>
<p>Keep in mind that you’ll also need LORs from professors who can speak to your ability in the field. So while it might be possible, the odds are probably stacked against you if you don’t have some upper level physics. </p>
<p>Your best bet is to talk to Physics/Astronomy profs at your school and come up with a plan to show how you meet the basic requirements.</p>
