I failed out of an ADN program once. I had to have an 80% or above by midterm and i had a 79%. I felt bad. so the next school i went to i learned different study habits. I would read the material, make out lines of the chapter. know s/s of diseases. learn the diets to the disorders. get a nclex review book. (saunders is good). review the disorders you are learning in class in saunders. ask the teachers if u don't understand. get a study group going..not to many people. go to after school tutoring if available. make time to study (early morning, late nights) eat well, get plenty of rest. You will do fine.
