there should be more time because its hard to write out these equations. also it took me a couple second to realize what you wanted (derivative, indefinite integral...) and the command form derivative is derive not derivate

29.5 seconds yeah I agree more time needed. I may tell my calculus class it's for a grade though to totally freak them out.

The description should say "DIFFERENTIATE these FUNCTIONS in under 30 seconds". I might suggest making a longer quiz with like 20 questions of different types (trignometric, logarithmic, exponential, rational functions, etc...), with more time of course.

did it with 0:06 seconds left, only because I differentiated beforehand and then typed as fast as I could.

I need more time. I differentiated and typed the first two with 3 seconds remaining!
