Hi Aryan,

If you have taken PCB but your hall ticket gives you PCMB, you can discover that it is a clerical error or the way that you selected the subjects in the application. It is advisable to check with your school or with whoever the exam authority is as soon as possible to find out if this will affect your exam or your result. When you contact them, you should have a written proof that confirms your combination of subjects (e.g. your registration form, the school records, etc).
