Dear student,

If you take pcb then you will have a little bit maths in it. According to the entrance exams for pch students, the level of mathematical calculations is easy, but if you take maths then it will be quite tough if you do not like maths. You should think well in this situation because taking an additional subject might increase your burden so think wisely. The level of mathematical calculations is not that tough in physics. It will be a little difficult but if you really want to study mathematics then go ahead and choose it as your additional subject.
