Another way to work it is CLEP tests. If they don't accept a transfer credit for ... american history or whatever, but you took the class, and they do accept CLEP tests and those aren't terribly hard... Note there are exam fees and transfer fees to consider, usually nominal.
My personal experience at a couple schools is the smaller the school the more often exceptions will be granted. Or maybe rephrased across all sizes of school the (someone) will grant 10 exceptions per year and maybe 1% of students will try to get an exception, which is awesome odds if its a 500 person private college, not so awesome odds at a larger 5K person school. So even if on paper, calculus won't transfer, if you make a bit of a pest of yourself the dean or dept chair will eventually sign off. Also you can game the system, OK you won't accept my calculus transfer credits, very well, I will get instructor permission to take diffeqs without pre-reqs and when I pass diffeqs I will petition the dept head yet again for calc credit.
