I would assume that because this is a timed exam and you only have six minutes per problem, I cannot see there being any involved calculus problems such as having to integrate an indefinite integral using integration techniques such as partial fractions expansion coulped with trigonometric substitution. Even if they gave a problem that you had to integrate, I would imagine that it would be a simple definite integral in which you can solve using either the Casio FX-115 or the TI-36X Pro, which are both approved calculators.
