I'm glad that it helped you study SQL, which you needed when you got a job! I'm even more proud that you said it wasn't difficult to take. I'm preparing the next level of advanced lectures, and it seems that it will be in the form of solving SQL query practice problems using various patterns. Thank you again :) If you have any questions, please contact me at any time. + Is there anything else you would like me to cover in the advanced lectures? Please let me know at data.pelican.joe@gmail.com. Thank you :)
