Hello Naengmu. I compiled what I consider the most fundamental aspects based on my experience and knowledge, and it seems there was a lot of overlap with the ISTQB syllabus. Unfortunately, this course was not designed for those who are already fully familiar with the ISTQB syllabus. It was created for those exploring the field, such as aspiring developers or people looking to transition into IT from other industries. Since I also belonged to the latter group, I wanted to be of help to them. Based on your message, it seems you are already putting in a lot of effort and thought into this. If you have any questions regarding your career, please leave them on the Q&A board, and I will share my modest opinions. Taking your review into account, I will strive to improve not only the content of future courses but also ensure that the information for each course is more clearly defined. Thank you for taking the course and for leaving a review.
