Since Becker doesn’t include one, how did you practice doing a TBS for a government wide financial statement ?

As the title suggests, I need tips on how to practice this type of TBS for FAR. I take the test in 1 week and I’m kind of scrambling trying to do as many mcq and TBS as I can. I saw somewhere that some people have gotten government TBS and now I’m freaking out because Becker barely talks about this. What did you guys do to learn how to tackle this sort of sim? Thank you!
