Singaporeans and Singapore PR -Singapore Citizens / PR students should continue their mother tongue languages, if they wish to study in local university under the MOE Mother Tongue policy. In most cases this will be the language they studied for their PSLE.
Non Singaporeans -Pupils who are not Singaporean (or Singaporeans who can provide an exemption letter from the MOE) are still required to study a second or foreign language.
Students exempted by MOE from their Mother Tongue Language are required to do a language at ACS (International). It can be a foreign language.
The last 3 Languages are FOREIGN LANGUAGE OPTIONS. (Native speakers of one of these languages should choose one which is a foreign language to them.French or Spanish can only be selected if you have studied these previously as a foreign language.)
