ATI & PoP NCLEX

[nursing327]

I'm a first year nursing student and my class has been trying to figure out how ATI works. We had our first ATI exam yesterday and our grades are blocked until all finals are done. On our ATI accounts, it's showing a percentage of our probability of passing the NCLEX even though our ATI exam grade is blocked. How does the ATI system, ATI Pulse, and the probability calculator work? We were told the probability tells you how you did on the exam even though the grade is blocked, but when we asked upperclassmen and faculty no one was sure. Also, any tips on how to prepare for ATI exams is greatly appreciated. Before yesterday I felt prepared and after the test we all felt as though we did terrible!
