Studying astrophysics is possible with a background in physics alone, though having A-levels in all sciences and math is preferred for higher-ranking universities in the UK. Job opportunities for those with a bachelor's in astrophysics are similar to those with physics or math degrees, including roles in finance, teaching, government contracting, and software design. A PhD is often necessary for serious research positions or permanent university teaching roles. Concerns about not having studied other science subjects are valid, but many have successfully transitioned into astrophysics with a physics focus. Overall, a strong foundation in physics and math can still lead to a successful career in astrophysics.
