DSST substance abuse - Petersons score?

[xiguassux]

I took the first Petersons substance abuse DSST test today... I know the ACE passing score is 400 but the site scores the test on a percentage basis... is there a scale somewhere which converts the score to tell me if thats equal to 400 or better? I got 60% (60/100)

Sorry for my ignorance but this is my first DSST test. Also, does anyone know other free test sites for this one?

Thanks!
