I should have done maths degree , some of the elec engineering subjects I do are kinda hard , but maths is just maths , reckon I could have got better marks at it.

Only problem is that a maths degree is kinda useless for getting a job, plus it would get boring after a while

Answer 38

fun? who said it was fun *faint* O_O

Answer 39

no elec wrong......m screaming

Answer 40

why are you screaming lol?

it would be easier for a engineer to swap with a mathematician, than it would for a mathematician to swap with an engineer.

For starters engineering involves group work and gets quite stressful at times, whereas maths is all independant

mathematicans can do stuff engineers can't do , engineers can do stuff mathematicans can't do, CS majors can do stuff engineers can't do and so on ~

Answer 98

you're a guy uzma :)
