Hello,

Yes, it is possible to change to a government school in Trivandrum for Class 11 with PCB (Physics, Chemistry, Biology) and Computer Science as an additional subject, but there are some conditions:

1. Eligibility : Most government schools require Mathematics for Computer Science. Some may allow without it.
2. Admission Criteria : Merit-based; your Class 10 marks matter.
3. School Policies : Check with the specific school if they permit PCB with Computer Science without Mathematics.
4. Kerala State Board Rules : Some schools under SCERT may have restrictions.
5. Alternative : Consider Informatics Practices instead of Computer Science.

Hope you find it useful !
