Introduction to business DSST

I have self tested with the Peterson off line test and received a 64% does this seem high enough to pass the main exam?

I have noticed that the Peterson offline tests seem harder than the real deal, does anyone have any feedback on this.

You should be fine with a 64% Peterson's score IMO. This particular test had a lot of "common-sense" type questions. I've found that Peterson's is always harder.
