  • This course is great for people with no prior knowledge on SQL. I feel that it digs deep without overwhelming you with too much information and you can really learn at your own speed. Great overall.

  • I really enjoyed how the course touches on the essential with just enough context. It was exactly what I was looking for to start using SQL to query data the next day. The practice ground and guide was very useful as well

  • I learned SQL in my college course but I liked they way codecademy taught it a lot better! I liked the visual graphics of how the tables transform when they merge together since I have issues visualizing the actual changes.
