I just finished the GRE. Like others, reading through this thread helped to reassure me when I was studying and so I'd like to share my scores as well.
 
	So I actually only took three practice tests in full. In chronological order:
 
	PowerPrep 1:    159 Verbal  169 Quant***
 
	Manhattan 1:     165 Verbal  159 Quant
 
	Manhattan 2:         n/a          166 Quant
 
	Manhattan 3:     163 Verbal   162 Quant     (about a week before the actual exam)
 
	Actual:               167 Verbal   167 Quant
 
	***The169 Quant score that I got on Powerprep 1 was aberrant; I just got really lucky with guessing. I took this test about two months into my studying and I was certainly not at a 169 level of math understanding at that time.
 
	I wouldn't necessarily call the practice tests any easier or harder than I saw on the day. The Manhattan test vocabulary is certainly more obscure than what I saw on the test though - I think Magoosh practice was better for that.
