Opinion on 3rd party free practice tests?

Hello everyone,
I am currently on the 8th week of the 2-month GRE preparation plan, and I see that most of the action items on this week are related to strategy / time management. I have about 15 days (test day - 19th August) and would like to practice time management and spend some time getting familiar with the interface.

Since there are only 2 free PP tests available (one of which was exhausted in the first week), what are your opinions on the free practice tests provided by 3rd party test prep companies? Is it worth doing those and if yes, what kind of mindset should I have while solving them?

Thanks in advance!

You can use them for improving time management and increasing you’re sitting habit but don’t use them as the criteria for judging how well your preparation is going and if you’re the type to get stuck if you see low scores then I will just avoid them totally.
