So are you interested in Data Science but not sure where to start? Here’s a breakdown of a few steps and resources to help you gain a foundation to pursue your studies or undergo a career change into the trending and lucrative field of Data Science.

1. Start by brushing up on your Math

Calc I-II
Professor Leonard’s videos – he is the best resource for Calc I and II in my opinion
Paul’s Notes  – great for practice sets and for clear notes
PatrickJMT’s YouTube account

Linear Algebra (books)

Linear Algebra from Saint Michael’s College
Linear Algebra Done Wrong

Statistics Foundation
Intro to Statistics 
Stanford’s online Statistical Learning with R

Probability, preferably using R (books)
