Where can I learn Data Science and Get certificate for free

Question

data science(python, R, Sql)

Answer 1

There are numerous sources to acquire the knowledge, but free certificates are rather *worth*less than *price*less :)
Just focus on learning and doing real projects afterwards. Believe me, those are worth tons more than the nice-looking PDFs ;)

Try: www.kaggle.com/learn for starters

Answer 2

I want to learn sql

Answer 3

All should be there, in the Kaggle courses :)

Answer 4

Data Camp is a good place to learn Data Science too, although it doesn't gives out free certificates, as far as I know. Still, the courses are good and worth the price.

Answer 5

I'm doing some courses on edx, they are well made and you can audit for free.

Answer 6

i dont know but it is a good start to begin with self learning
