This is the second part of the blog I posted about my personal choice of best Mathematics apps for students taking up Engineering and B.S. Math courses.

During my college days, Calculus is one of the hardest subjects that I have ever encountered. Good thing our Calculus instructors were so bright that they were able to explain the principles effectively, so I passed my Calculus subjects and learned so much about it.

Our students of this generation are lucky because there are plenty of apps and online resources that could help them study Calculus even if they're away from their instructors. Add these apps to their books and notes, they can now study anywhere at their most convenient time.

Let me guess, if you're an Engineering or B.S. Math student and you've landed on this article, that's because you are looking for an alternative solution on how will you speed up your learning process in your Calculus subjects using relevant apps.

Let me introduce to you Ximarc Studio's Khan Academy. Khan Academy provides video compilations of various Mathematics topics like Algebra, Trigonometry, Chemistry, Physics and Calculus. On this article, we are going to concentrate on Calculus topics.
