Absolutely terrible. They direct you to watch free third-party videos on youtube, then assign a problem on a topic which wasn't covered in those videos, with unspecified input parameters and unclear output. The objective is to use a particular Java class. But are you using it correctly to actually benefit from multithreading? Who knows!

With no instructions and no criteria for success and failure, do not expect valuable feedback. If you get a passing grade, it's because your program compiles, which is something you can already see on your own, no course necessary. Avoid, avoid, avoid.

Курс классный, заставляет думать и искать, здорово, что задания немного сложнее лекций и нужно прям честно поработать)
