Is an IGCSE in add maths mandatory to study in Singapore?

Im taking my IGCSEs this year and i heard that Add Maths is mandatory to study in Singapore. I suck at Add Maths so im planning on dropping the subject and focus on Maths instead. Can I still study in Singapore without an IGCSE in add maths?

Im planning of studying something related to biology, not engineering tho.

Im planning to further my studies at a polytechnic college, maybe at Nanyang Poly or Ngee Ann Poly.

Hi, if you are looking into biology related course such as health science and applied science and looking into polytechnic college entry requirement, the entry requirement from IGSCE is English Language (EL1), Elementary or Additional Mathematics and any one of the science subjects.
