Need help with ETS practice test

Hello, I have started practising the questions from the official ETS book however, I am having a hard time understanding the explanations to the answers. Is there any tab on the Gregmat site that has a consolidated walkthrough of the GRE practice tests? I’m aware of the old gre walkthroughs but i was wondering if there’s anything like that for the practice tests that is in the ETS GRE book.

No, but you can usually get some explanations by typing the question on the internet.
