Today, I finally completed this long course and am leaving this review. First of all, this course is one I can highly recommend to Java backend beginners. The course content assumes you've completed the basics (database, Java, web frontend) once, and focuses on web programming starting from JSP through Spring Boot. It follows the lengthy curriculum of a traditional offline academy, which is why the course exceeds 60 hours. Since this isn't an online-exclusive course but rather appears to be an offline bootcamp lecture from a private academy transferred as-is, it boasts incredible detail matching its length. (If this content was delivered in a government-funded program, those students hit the jackpot!) When I attended a government-funded academy in the past, I had doubts watching them rush through Spring in just 7 days, wondering "Is this really right?"... This course's quality feels like an offline bootcamp class from a private academy that would cost hundreds of thousands of won. It's not just long for the sake of being long - it thoroughly covers everything from A to Z, working through numerous examples to solidify understanding as close to perfectly as possible. The reason other instructors' Spring Boot courses feel like hitting a wall or being hard to understand mid-way is because those courses are designed as online-exclusive content, streamlined at the instructor's discretion. This course, being a recorded bootcamp academy class actually delivered offline, operates at a different dimension of detail compared to other online-exclusive Spring courses. This conceptual difference means you're getting content equivalent to at least 600,000 won per month minimum, for a course that would normally span at least 2 months - and you can study it with unlimited repetition at this price point. This is what I consider a success of online education! You'll have a learning experience with a perfectly thorough Spring course that's worth every penny. The reason there aren't many instructors who productize actual academy lectures is that many courses on Inflearn are created by current developers doing teaching as a side job. This course stands out from other Spring Boot courses because it's delivered by a professional instructor specialized in teaching, with content refined through years of accumulated classroom experience and expertise as a dedicated academy instructor. From A to Z by one instructor - I have no doubt this is the best choice for beginners, being an offline field lecture from a professional academy instructor specialized in teaching numerous students over many years. I could feel the instructor's teaching prowess built from years of experience, capturing the common difficulties many students face and ensuring those areas are thoroughly reinforced. I hope the instructor releases more advanced-level content in the future. I really learned a lot. It was tremendously helpful.
