Absolutely. In the first couple blocks I had about 20-25 minutes to go over my answers. By the last block I had maybe 5-10 minutes. I caught many mistakes in those first few blocks with careful review, probably not so many in my last blocks.
I didn't do any practice tests as I felt they were a waste of time relative to studying or doing question banks. No matter how much you simulate, 8 hours is going to be a long time. Just get plenty of sleep the night before and ration your break time during the test on the later blocks.
