Qualification: BSc

Faculty: Science

Duration: 3 years

School: Physics

Study mode: Full-time


Bachelor of Science in the field of Astronomy and Astrophysics: Programme code SBA15

Astrophysicists interpret astronomical data gathered by astronomers to understand how our universe works. Astronomers view the entire electromagnetic spectrum – called “Multi-Frequency Astronomy” – through optical telescopes, radio telescopes, microwaves, gamma-rays, and X-rays.

An exciting career awaits you in Astronomy and Astrophysics in South Africa, which was awarded the Square Kilometre Array (SKA) project.

This comprises a core of radio telescopes in the Karoo, and is one of many projects supported by our own South African Large Telescope (SALT), an optical telescope sited at Sutherland.

National Benchmark Test

All Faculty of Science applicants must write the National Benchmark Tests (NBT).

There are two tests - the Academic and Quantitative Literacy Test and the Mathematics Test. Your test results are used in addition to your Grade 12 results to identify students who may need additional support during the course of their studies.

Rules for the NBT

You must register on the NBT website, or via mobile phone, to write the tests. Registration closes about three weeks before each test date. You can register for the NBT before you submit your application to Wits. DO NOT wait for an official notification from Wits to register for and write the tests, because you may miss the end of September deadline.

  • The test fee can be paid once you have registered to write the test.
  • The tests must be written by 31 October 2023. You are encouraged to write the tests as early as possible.
  • For a comprehensive list of test dates, registration dates and available venues, please refer to the NBT website 
  • Both tests must be written in one session.
  • ONLY the first attempt results will be considered so we advise against writing the tests more than once in a year.

Application Closing Date: 30 September 2023 | Residence Applications: 30 September 2023
