How similar are the sample papers to the actual Practitioner exam?

The 7th edition workbook includes 2 sample exam papers. Are they about the same level as the exam or are they easier?

I think I’ve read that for the 6th edition the sample papers were easier than the actual exam, and I would like to know how things are in the 7th edition.

I’ve done them without much preparation and passed with a bit of a buffer, so I’m wondering whether I could already attempt the exam…
