Here are some reasons I recommend http://www.Datacamp.com over online learning platforms in Data Science
- World class faculty specific to each sub course and module
- High Quality -quizzes and videos make a high quality automated self learning environment
- Really really cheap – At 29$ / month its much cheaper than say paying 25000 rs for six weeks (65rs= 1$) or 2830 Rs versus 25000 Rs
