You can't select a branch on the basis of your interest in maths as it is needed in each and every branch of engineering as you have mentioned that you are not interested in physics but you have to study physics a bit in every branch so don't make your decision on the basis of your interest in hsc subjects have a look over all branch details and then find out your interest . I hope you understood my point

Hello Shiva,
If you have interest in math then you can choose Mechanical engineering or Civil engineering.
But if you are good in computer programming then you can choose CSE also.
Thank you.
