Update:
I am now done with all the sections (the most recent ADA sample):
The sample test was the easiest DAT test I have ever taken
SNS 100% (only missed 3 bio questions)
PAT top 1% (angles were a bit harder than usual)
QR top 1% (stupid mistakes)
RC an ok score if I give myself 20 min. instead of the 15 min they give....
(NOT sure if this is a good indicator: it was only one passage, time was 15 min, I knew a bit about electromagnets 😉 )
CONCLUSION: So, I agree with the fellow who said this sample test is a joke.
