Is it worth signing up for Yandex Practicum courses?

Question

Java

After a long break, I decided to return to teaching. I became interested in courses from Yandex Workshop on JAVA. I myself am currently reading Schildt and Prokhorenok, and also doing JavaRush. Tell me, who knows: is it worth signing up for these courses in order to gain knowledge and skills for further employment / enrollment in an internship. Or is self-study plus JavaRush enough?
