This is purely my personal opinion and is quite blunt. First things First, what’s your plans after Computer Science / Engineering. Is it going to be
- an RnD job, or some kind of Low-Level programmers
- Normal IT job(dev, QA, dev ops, admin), or
- MBA from IIM or any reputed institution.
If you are going to opt#1 – then there’s very extensive usage of Maths/Physics.
for 2&3 – You will definitely gonna ask your teachers – Sir , where do we use all those alpha , beta , gama theta, lemda lassan’s that you taught us.
