I’ve started to take an intro SQL class but I want to find more places to practice. Do any of you have recommendations for sites that I can use to practice creating queries based on pieces of information someone is looking for?

Any other advice to give to a brand new SQL learner?

Thanks in advance for any guidance.

Edit: Thanks a ton for the responses, I really appreciate it. I’ve bookmarked these pages and started to go through these sites.

Have a look at SQLServerCentral.com. Lots of articles and forums there. Of some importance is to think about doing things in sets, not one by one. For example, if you need to do the same thing to a bunch of rows, don’t write a loop to do them one at a time - you can usually do them all at once. Lookup RBAR (Row By Agonising Row).
