How to become a Physicist

Studies how the universe works, from particles to stars.

What does a Physicist actually do?

More about this career

Physicists study how matter and energy behave, from subatomic particles to astrophysics, mostly through research – academic, or at institutions like iThemba LABS or SAAO. Many physics graduates end up in applied, non-academic roles – engineering, data science, finance – because the analytical and mathematical skills transfer well.

Where this degree can take you

  • Research Scientist
  • Astronomer
  • Medical Physicist
  • Data Scientist

Rhodes University

BSc (Physics)

Science · 3 years

Rhodes points 45 points

  • English: 60% if it is your Home Language, 65% if it is your First Additional Language
  • Mathematics: level 4 (50% or more)
  • Physical Sciences: level 5 (60% or more) OR Life Sciences: level 5 (60% or more)
  • Life Orientation: level 4 (50% or more)

Raw-confirmed 2026-10-04 against the Rhodes 2026 Undergraduate Prospectus (pages 13-19): points bands, English and subject levels match. Rhodes points of 39-44 are considered at the Dean’s discretion; 45 or more receives a provisional offer. We show 45 as the qualifying number so that "you qualify" means exactly that - but you are still worth an application from 39. Rhodes has no Engineering and no MBChB. The NBT is recommended, not required. This is Rhodes’ general Faculty of Science admission requirement, not a Physics-specific published figure - you are admitted to the BSc and choose your major once you arrive. Life Orientation is not scored, but you need at least 50% in it.

UCT Science Faculty Points Score 660 out of 800 (band a)

  • Mathematics: 70%
  • Physical Sciences: 60%

Band A (guaranteed offer) is an FPS of 660. Band B (likely offer) is a WPS of 640 - the WPS adds a 0-10% disadvantage factor that we cannot work out from your marks, so we only check you against Band A. Band C (550) applies to redress categories only. All Science majors share these entry bands (Mathematics 70%+, Physical Sciences 60%+; NBTs in Mathematics, AL and QL must be written but do not affect admission). Admission is to the BSc and a major is chosen once you are in; selected students may be counselled onto the four-year Extended Degree Programme.
