rhdiddl1376's honest review, Hacking as a Hobby #3 (WebGoat) course

Honestly, I thought I would be satisfied with just learning SQL injection, but there were many unexpected contents, and they were explained kindly, so I was able to learn easily even though there was a lot of content. It doesn't just pick out the easy parts, but really includes all the contents. It even solves problems with real bugs...
