This is a 24 Day challenge hosted by Dawn Choo.
This challenge started on 1st Dec 2024, where you get new questions each day.
This is a good start if someone is practicing SQL at any level. The questions are randomized based on different levels (easy, medium and hard).
Best part is you can try to execute your query multiple times i.e. you have multiple attempts to solve the question and even you get hints if you get stucked in any of the question.
