Hii,

Yes, it is possible to change streams from Science to Arts after completing class 11th in the CBSE system, but there are a few things you need to consider:

1. School Permission : You will need to check with your current school to see if they allow stream changes. Some schools may have specific policies regarding changing streams between class 11 and 12.

2. Subject Availability : You must also confirm if the subjects you want to take in the Arts stream are available at your school. For instance, subjects like History, Political Science, Psychology, etc., should be offered.

3. CBSE Guidelines : CBSE generally allows changes in subjects, but they need to be done before the academic year begins or within a reasonable time frame. If the school gives you the green light, they will guide you about the paperwork and any specific process they follow.
