Hello

You have to choose a total of 5 subjects in your 10+2 , now if you choose PCB then you need to choose other two subjects as well.

Now what these two other subjects depends upon two things :-

• Your choice of subject
• Subjects offered by the college in which you are doing your 10+2

Now , a language subject is compulsory,  so your 4 the subject will be English.

You can keep your 5th subject as hindi or any other subject of your choice or depending Subjects offered by the college in which you are doing your 10+2.

Thank you
