Good places to learn SQL from? Datacamp not great
Is this SQL cheat sheet correct? Source from DataCamp.
Struggling with SQL self-study (Datacamp Skill Track) — feels like my brain just freezes. Any advice or resources?
DataCamp certifications are a joke and a waste of time
Does DataCamp offer Data Analyst Certification?
What is a Data Analyst?
Data analysts work with business stakeholders to provide actionable insights from data. They are typically using visualizations and statistical methods to understand and interpret data, identify patterns and trends and make recommendations. They will generally be using SQL and visualizations tools, adding in Python or R as they progress in their career.
How long are DataCamp Certifications valid for?
Our Career Certifications are valid for two years from the date awarded. The data industry is moving quickly and it is important to keep your skills up to date, so you will be invited to retake the exams after two years, or if you would prefer, you can attempt to upgrade to a more advanced level certification.

So I’ve been going over datacamp and have completed the intermediate sql and the course on Joins etc but recently I tried taking a test for a product firm that required SQL and most of the questions were on joins but I just scored a 12/22. Additionally I am trying to solve the intermediate questions on hackerank related to SQL and I am failing to do so. The basic ones were pretty easy.
I am wondering what resources I should look at to relearn SQL or maybe datacamp gets better as I progress? Idk. So far it seems to gloss over a lot of concepts but there is a lack of application. Or maybe I’m not very good at this and should just stick to corporate finance :/
