The book contains a lot of helpful content for work, such as AI utilization, tuning, and index policies. You must read the sections from the middle of the book onwards. I highly recommend it.

This is the best for reviewing concepts before taking an exam! I can't believe a lecture like this is... free...!!!! Thank you always..!!!

I bought this for the first time today, and it feels like we're studying together, which gives me more energy and makes it so much fun!!!

This was the lecture I've been waiting for. Thank you!!

I felt stuck when solving it alone, but as I work through it while watching the lecture, it's gradually making sense. I'll keep working hard until the end.

Thank you for the great content! I'll refer to it in the future!

The concept explanations are good and having problems included with each chapter helps with understanding.
