Hello,

So Honestly with only 50% it is hardly possible to continue with science stream in the future. In my opinion you yourself should not choose as it will be easier to focus on streams good for your future. Even if you really like science I would not suggest than because getting admission will not be possible and even if you go through management quota it will not help you. You could look for other options like law, journalism, arts. You could choose something creative which don't need any basics. These are also good courses and difficult to get but you won't have to face the struggle for not being able to fulfill the requirement of PCM or PCB.

Good luck.
