Second Major in Computer Science
The School of Computing offers a second major in Computer Science (CS) for non-School of Computing students.
Objective
The objectives for a Second Major in CS are as follows:
- To provide a computer science programme within NUS for non-computing students;
- To contribute to the national focus on growing the pool of technical ICT specialists in Singapore;
To produce graduates who are able to understand computer science principles and practices and apply it in a multi-disciplinary context.
Student Learning Outcomes
The Second Major in CS enables students to attain, by the time of graduation:
- Strong knowledge of computer science foundations and fundamentals, including (a) familiarity with common computer science themes and principles, (b) high-level understanding of systems as a whole, (c) understanding of the theoretical underpinnings of computer science and their influences in practice.
- Individual competence in applying sound principles and rigorous thinking to (a) analyse an application problem, (b) understand user’s requirement, (c) formulate the problem in terms of computation requirements, (c) conceive novel solution ideas, (e) design appropriate solutions that meet the requirements, (f) implement the solution, (g) evaluate the effectiveness of the solution.
- Strong communication skills and ability to work with, and contribute to, a multi-disciplinary team to bring a range of technologies together to develop computer systems and solutions of multi-disciplinary nature.
- Ability to engage in continuous professional development.
Admission Requirements
Cohorts 2021 onwards
Existing students who have obtained B+ or above in CS1010 (or its equivalent) and CS2040 (or its equivalent) may apply for the second major by submitting an application to the School of Computing by their 4th semester of study in NUS. Students who are directly admitted to the second major during admissions exercise must obtain B+ and above in both CS1010 (or its equivalent) and CS2040 (or its equivalent) to continue in the second major in Computer Science programme.
College of Design and Engineering students are precluded from pursuing Computer Science second major. They may pursue minor and second major in Computing offered by their home faculty. Students from earlier cohorts and were admitted to the computer Science second major will continue to fulfil their outstanding requirements. CSxxxxDE version courses will not be considered as meeting our Computer Science second major requirements.
Cohorts 2017 up to 2020
For students from cohorts 2017 till 2020, those who have taken CS1010/S/E and CS2040/C/S as either part of their degree requirements or Minor in Computer Science can apply for entry into Second Major in Computer Science if they obtain B+ or above in both courses. Students who are directly admitted to the second major during admissions exercise must obtain B+ and above in both CS1010 (or its equivalent) and CS2040 (or its equivalent) to continue in the second major in Computer Science programme. Students pursuing the BEng (Electrical Engineering) programme are precluded from reading this second major.
Cohorts 2016 and earlier
Students who has taken CS1010/S/E and CS1020/E as either part of their degree requirements or Minor in Computer Science can apply for entry into Second Major in Computer Science if they obtain B+ or above in both courses. Existing students who have yet to embark on CS1020/E can apply for entry into Second Major in Computer Science if they have obtained B+ or above in CS1010 (or its equivalent) and CS2040 (or its equivalent). They may may apply for the second major by submitting an appplication to School of Computing by their 4th semester of study in NUS.Students pursuing the BEng (Electrical Engineering) programme are precluded from reading this second major.
Application
School of Computing Minor/Second major are restricted programmes which students must apply during the prescribed application window specified by the School via EduRec. Students will not be able to declare themselves in the Academic Plan Declaration Exercise (APAD) before ModReg begins for each semester. APAD is only for open minors/second majors which do not require special approval from the host department to approve.
To apply for School of Computing minor/second major programme, students must submit their application to the School of Computing by the 4th semester of study, for enrolment at the start of their 5th semester of study.
With the recent revision to total unit requirements for Minor and Second Major programmes, the School is making special provision to allow students from Cohort 2019 a final application round to apply for School of Computing minor/second major programmes in Sem 1 AY21-22 only, for enrolment at the start of Sem 2 AY21-22. Any late request to enroll after our application window has closed will not be entertained.
Please take note that the application date will typically be from the Friday (9:00 AM) before reading week of each regular semester till end of first week of examinations on Sunday (11:59 PM), based on NUS academic calendar here. Kindly refer here
for more information on the application procedure for restricted programmes.

Continuation and Graduation Requirements
The Second Major in CS is a non-Honours major programme. Students cannot use NOC internship credits (TR coded courses) to map to the second major requirements.
The Second Major in CS will be awarded to students who have completed the total units of second major requirements they belong to. It would be either 48 units and 40 units respectively for the cohort they belong to. That is, 48 units for Cohort before 2019 and 40 units for Cohorts 2019 onwards. Students will need to complete the primary major requirements to graduate.
The programme structure for Cohort 2021 onwards is given below.
The Second Major in CS is structured as follows:
- Computer Science Foundation = 28 units
- Computer Science Focus Area Electives = 12 units
