I took it last fall. We weren't given much time to prepare for it and were worried, only 1 out of 40 didn't pass and she was given the chance to retake the part she didn't pass.
I honestly don't remember much about it because we had those 3 tests in the morning then our cardiovascular systems and drugs tests that afternoon, we were there from 8-5 that day. It was a horrible day that I've blocked from my memory.
I do remember one particular section that no one finished, we just bubbled in the rest. Consider this, ALL tennessee tech students will take this test and most aren't nearly as hard as nursing.
