[MESMHS]

My school changed our curriculum/standards in my last semester of RN school. The grading scale was raised from a 75% to an 80%. Also, they decided to implement the ATI comprehensive predictor exit exam. By the time we received the information and study materials we only had six weeks to prepare until we have to take the exam. We must receive an 80%. If we don't pass on the first try we have the opportunity to retake it the morning of graduation. If we don't pass on the second try, we don't graduate! My whole class is extremely nervous about this test that is going to decide whether we pass or fail regardless of our grades thus far.

Can someone please tell me if there is a chance we can obtain an 80%... We have to take it Tuesday (3 days away)
