My advice is continue studying at a jc. It’s better to be under the supervision of the school, although you might think that this jc isn’t that good, you just have to bear with it and work hard. It’s much much harder to do well by yourself self studying

Go call up nus. You have to find out whether it is recognized, if not you’ll be wasting your time studying

It is first of all easier, so u have to get a higher grade if you want to get into the courses you mentioned.

The grades required for to enter local uni is different for Cambridge international a level and sg a level… Call up schools to check… Cause the international is supposedly easier
