No, it is highly unlikely that you can change your stream from PCB to PCM after your CBSE 12th admit card has been released; the chances are practically zero (0%) as CBSE policy usually does not allow subject changes once the admit card is generated.

As a Class 12th PCB student from CBSE, you're wondering if it's possible to change your stream from PCB to PCM after the admit card has been released.

## CBSE Rules and Regulations

According to CBSE rules, students are allowed to change their subjects or streams only up to a specific date, usually before the admit cards are issued.

## Admit Card Release and Stream Change

Once the admit cards are released, it's highly unlikely that CBSE will allow you to change your stream from PCB to PCM. The admit card is a confirmation of your registration and subject choices.

## Possibility of Stream Change

Given the circumstances, the possibility of changing your stream from PCB to PCM after the admit card has been released is:

- *0%*: CBSE is unlikely to allow stream changes after the admit card has been released.

However, I recommend checking with your school authorities or CBSE regional office to confirm the possibility of stream change. They might be able to provide more information or guidance on this matter.

Keep in mind that even if you're unable to change your stream, you can still explore PCM-related courses or careers after completing your Class 12th with PCB. Many institutions offer bridge courses or foundation programs to help students transition to different fields.
