O-level examination
If you are a high school student whose grades are around the second line, then the O-level exam may be suitable for you. This exam is equivalent to the senior high school entrance examination in Singapore. Your grades can be used to apply for ITE, Singapore Institute of Technology (equivalent to junior college) and junior college (equivalent to senior high school).
Advanced level examination
If you are a high school graduate or a freshman, the A-level exam may be more suitable for you. However, please note that this exam is very difficult, and your college entrance examination score must be at least one level before you can try. A-level scores can be directly applied to public universities in Singapore, and of course you can also apply to first-class universities in other countries.
International recognition
Whether you choose O level or A level, your achievements are internationally recognized. Although the degree of Institute of Technology is a junior college, it has high gold content and recognition, and it can also save you time and money. You can still apply for undergraduate and master's degrees in the future.
