Do you know any (full) mock test which is considered easier than others? I will save it for the last week to boost my motivation 
Maybe Schweser mock test 1, book 1 is the easiest among the 6? Any mock test from other providers is easier than this one?
I looked back at my 2017 study log, and I did better on Schweser Volume 1 exams 2 and 3 (50/60 and 49/60 respectively) than I did on exam 1 (39/60), so 2 and 3 were easier for me apparently. I didn’t do any other 3rd party mocks though so I don’t know where they fall difficulty-wise.
