I am a Singaporean A lvl applicant matriculating this year and I managed to receive offers for Math + CS double major from both NUS and NTU. NTU has also offered me the Nanyang Global Scholarship.
For ntu the scholarship gives 6500 a year so 26000 over the entire course. Also helps with expenses for laptop and hall. However I heard horror stories about CCDS curriculum/admin/bureaucracy issues.
For nus I wld say that there is a stronger computing culture and more clubs which are relevant to my interests. There are also alot more specialisations, better SU system and location more convenient compared to NTU.
I am not too concerned about social life or hall cos I mainly want to focus on my interests and other projects. My family can afford the tuition fees from both schools.
Would appreciate it if anyone is able to give me advice on this!
