In Singapore, Junior Colleges (JCs) offer a two-year pre-university program for students who have completed their GCE O-Level examinations. There are three different streams available in JCs:

1. Arts Stream: The Arts stream is designed for students who are interested in pursuing a university degree in fields such as humanities, social sciences, law, and business. Students in the Arts stream typically take subjects such as Literature, History, Economics, and Mathematics.

2. Science Stream: The Science stream is designed for students who are interested in pursuing a university degree in fields such as medicine, engineering, science, and technology. Students in the Science stream typically take subjects such as Physics, Chemistry, Biology, and Mathematics.

3. Mixed Stream: The Mixed stream is designed for students who want to keep their options open and are not sure which university course they want to pursue. Students in the Mixed stream typically take a combination of subjects from both the Arts and Science streams.

In addition to the three main streams, JCs also offer a range of co-curricular activities such as sports, music, and drama, as well as leadership and community service programs. Students can participate in these activities to develop their interests, skills, and character, and to broaden their learning experiences outside the classroom.
