I have a few recommendations. If you're using IGGY for your med-surg I recommend getting the workbook that goes along with it. It is FULL of NCLEX style questions and I had a 10 point exam score increase when I started including this workbook in my study plan! I also recommend a nursing diagnoses book, I was not informed that this would be helpful and spent my first 3 semesters googling EVERYTHING. When I posted a link to a nursing diagnoses book that I found on google books, my classmates laughed because they had been using it all along (thanks for the tip guys!!...not!) Lastly, I would invest in Davis Drug guide even if you aren't required to. I just recently purchased it and am so excited because it includes so much info that the free apps like medscape and eporates don't include (nursing implications, patient and family teaching) Hope this helps, and good luck!!!
