A bachelor’s degree in Science is an undergraduate route that can lead straight into work or into further study later. It suits applicants who want a broad first degree before deciding on a more specialised path.

The universities differ in ownership and setting. One is private and in Cambridge, with published tuition of USD 48,500; the others are public, and city details are missing for all except Cambridge, so location should be confirmed with each university.

Before applying, verify the full tuition, entry requirements, application deadline, and the exact Science programme title with the university. Confirm the campus location, because only one city is specified, and make sure the programme you want is available for the year you plan to start.
