I decided to postpone my university graduation to pursue a career in marketing, specifically in CRM marketing or data analysis. While looking through job postings, I realized that SQL is highly in demand, so even though I am a liberal arts major, I decided to challenge myself with SQL for the first time. Thanks to an instructor with excellent teaching skills, I went from knowing absolutely nothing at the start to being able to use JOIN functions by the end. Of course, real-world practice might be different, but I am truly happy just to have built this level of knowledge. Above all, I am so grateful that such a high-quality lecture was provided for free. Thanks to the instructor, I was able to learn SQL concepts in an enjoyable and solid way! Because of you, SQL has become an interesting and fun tool for me. Thank you!! I highly recommend this to any SQL beginners!
