Hi there, I know how feel, I also missed the mark by a few points. I used the teas manuel to study also but it just didnt hit the mark(too vague) and thats weird since it is from the same company. Im now using the Mcgraw hill-Ged reliable comprehensive study guide---I am so happy to have found this. Its like every question from the test is covered in this book... also I took the ADN version but I think it will help with the BSN test too. As for the cost, try testing with your local community college usually their exams are reasonable priced. Good luck and try again
