Don't feel bad about HESI, 1st time I took the test I scored 780 fortunately my college did not require us to pass with 900. I took so many sample NCLEX tests and I always scored in the 70's I was so worried about failing the NCLEX but in June I sat for the NCEX and I passed. I can't explain why I would do so bad on practice tests but pass NCLEX. I did study for 3 weeks everyday for at least 5 hours. I just kept doing test questions, the books I used were NCLEX for Dummies, Lippencott's, and reviewed the HESI book. I hope that this helps some and good luck, you can do it!!
