Do you think that Physics A Level should have calculus?

Absolutely - this is what you'd use in reality.
I do A-level maths and FM too so it really pisses me off sitting there estimating the area under a curve by counting f*cking squares like a child when we could just integrate.
There is someone in my class who doesn't do a-level maths so they'd disagree, but capping calculus to an AS maths level (ie just basic polynomials) would be fine as it's easy to learn.
