When introducing the functions of each tool, he explained each one in detail while also letting me know how much of it is used in the work. It was really nice that he explained in detail the functions that must be known when actually working at the company and the functions that he himself frequently uses. It was nice that they prepared examples with a variety of cases so I could learn meaningfully without getting bored. I highly recommend this lecture package to those who are new to modeling or those who did it a long time ago and need a review.
