Hello Ishara Raju

If you son studied PCB in class 11 and class 12, and he want to study bsc gaming and coding in graduation so I'll suggest you to include information technology in external subject as it would be helpful for him while doing bsc gaming and coding.

He can also pursue bsc gaming and coding without IT subject and with PCB subject but if he studied IT in class 11 and class 12 then it would be really helpful for him.

Suggest him to take IT with PCB subject.

Hope this information would be helpful for you and your son.

All the best to your son for his bright career
