Preparing for Data Science

Data Science is a very hot area of employment right now. Being a Data Scientist basically means you are a programmer and a statistician/mathematician, and you can apply the knowledge of both worlds to tasks involving large amounts of data.

In order to start on a career path towards Data Science, you need all of the courses in the first two years of university calculus.

Yeah, you need all of them! Calculus I, Calculus II, Multivariable Calculus, Differential Equations, Linear Algebra, and Probability Theory (Calculus-Based Statistics). There are no short-cuts available if you really want to be a data scientist. You need to be both a serious mathematician and a master programmer.

There are many websites around that suggest you can get all of this mathematics knowledge just from the free MOOC courses available around the internet. This recommendation seems unrealistic - there are also lots of mathematics books available at the library and at used book stores, but trying to make your way through those math books by yourself .... that is a tall order.

Plus, if you do take the MOOC route and then you wish to actually complete a Data Science certificate or academic degree, proving that you have the requisite mathematics knowledge is ... not as convincing as having these academic courses completed and showing on a university transcript!

I completed the Linear Algebra course as a prerequisite to an M.Ed program in Mathematics. I worked entirely at my own pace, it was cheap, I actually learned the material. This was not a "pay your fee, take your B" type of class. I had to demonstrate true understanding in order to earn credit. Dr. Curtis was responsive and helpful when I had questions. All in all I would recommend this course and any other Distance Calculus course.

I needed to finish the Business Calculus course very very very fast before my MBA degree at Wharton started. With the AWESOME help of Diane, I finished the course in about 3 weeks, allowing me to start Wharton on time. Thanks Diane!

Courses Completed: Calculus II
The course material was well explained through the videos and notebooks, and it was nice to receive feedback on each assignment and correct any mistakes. However, the software required for the course was ridiculously outdated, to the point where I had to reinstall a very old operating system on my computer to even be able to run it. It was annoying and tedious to use, and it sometimes crashed. The graders were also sometimes overly picky about the way that concepts had to be explained to be considered correct (specific wording, etc), but it wasn’t too bad. Having multiple final exams seemed a bit excessive but again was not too bad. Overall, the main strength of this course is that it is completely asynchronous and self-paced, so I do recommend it if that is the most important factor to you. You will learn all of the material thoroughly, but you must be willing to deal with the more annoying aspects of the course (primarily the outdated technology).

After two failed attempts at my university, this course helped me understand Calculus. The live maths tool along with Dr. Curtis were especially helpful, allowing me to visualize concepts and expand my understanding. The explanations were clear, the examples practical, and I could learn at my own pace, which built my confidence. Thank you.

Great course. Professor Curtis and the TAs graded quickly and gave really helpful feedback that made the class feel smooth and manageable. Definitely recommend it.
