Through my company's internal training program, I chose to take the ADsP certification prep course on Inflearn. As more companies require data literacy, I felt that I must obtain the Associate Data Semi-Professional certification, and this course was a huge help in achieving that goal. I studied for about an hour to three hours after work for a month. I didn't get a perfect score, but thank you for the high-quality lectures and materials that helped me comfortably reach the passing score for the certification.

Thank you for the great lecture!

The curriculum is really good.

Thank you for catching all the details so thoroughly!

The lecture quality is poor.

The lecture quality is not satisfactory.

Thank you. Thanks to you, I passed!

It was very helpful. Thank you.

It was great that both detailed lectures and summary lectures were provided!

In 2023, the instructor's course was opened at my company, so I applied, received the textbook, and watched the videos once. I took the exam this time. Rather than studying mainly with summary books, I think properly watching separately offered courses would help build concepts and prevent being shaken even when facing difficult questions. I took the exam today and I'm not sure about the pass/fail result, but I think I was able to get the recall questions right because I remembered "pretty," "actual," and "sensitive" 😊
