Have you tried using WolframAlpha? If you get the pro subscription (~$66 per year - ~$45 a year for students) you gain access to their step by step solutions and unlimited problem generator. I am currently studying a Masters of Biostatistics (which has a heavy calculus section) and found this service invaluable.
