Hello, teacher? I am finally leaving a review. After passing the 7th practical exam with great enthusiasm, I challenged the 8th exam and passed. For the 7th practical exam, I bought a textbook and studied by memorizing all the codes in the textbook. However, on the day of the exam, the codes in my head were all jumbled up and I couldn't use them properly, so I suffered a bitter defeat. When preparing for the 8th re-examination, I took the teacher's lecture. I took the lecture at 3x speed for 4 days. And I studied by solving the materials provided and comparing the source codes every time I took the lecture. Using the tips the teacher gave me during class, I was able to solve the problem in 1 hour on the test day and got 90 points. (I was the first to leave the test room I was in haha) What was helpful about the teacher's lecture was that 1. Consistent writing method can be applied - My previous study method was to memorize the codes in the textbook and blog, so I had to memorize numerous codes for the problem, but through the teacher's lecture, I was able to prepare as a single process to prepare for any problem. 2. Data provision - The data provided are blank spaces and source code colab files. After attending each lecture, I was able to quickly get a feel for it by writing code directly in the blank space file, executing it, and comparing it with the source code file. 3. Task 3 - With the tips given in Task 3, I was able to memorize 3 lines of code and get 20/30 points. 4. Email - The information about the exam that you sent me via email a week before the exam was very helpful (especially the mind map). Thanks to you, I was able to obtain the engineer's license and also develop my skills in AI development, which I am currently working on. Thank you!!!
