I keep failing classes which are frustrating. I study hard, reading all the chapters, study the powerpoints and do nclex questions, but it does not help. What I am having a problem at is I do not know and understand how to apply concepts, and when I take the test I am down to 2 answers that look right, and not sure which one to pick. Please help. I have 4 kids and my teacher was thinking that was the issue but it is not. I am depressed and feel stupid at this point.
