Science (BSc)

Program Overview

The UCD Science common entry course offers a range of degree subjects leading to a BSc degree in one degree subject. Subjects are grouped thematically in streams. Students who are interested in exploring a number of streams in First Year can select the Explore Multiple Streams option. If an applicant selects Explore Multiple Streams, they are offered the same First Year module guarantees as students who choose one of the thematic streams.

In round 1 of 2026, places went to applicants with 540 points or more. UCD does not publish how it scores the IB. On Trinity College Dublin's indicative scale for the IB, that is about 40 points, or about 38 with Higher Level Mathematics at 4 or better, which adds 25. Applicants from outside the EU apply to UCD directly, where 33 points makes them eligible to compete for a place.
