I had the Saunders Q&A CD and I could click on every topic and then click study and it would bring up a test bank of 3,000+ questions. I would do my 100 questions and be done. It bookmarked where I left off and I could pick up where I left off the next day. Does yours not give you an option to bookmark or click every topic? I wouldn't focus on a specific body system, I would focus on safe and effective, physiological etc...Those are the area's I would check mark.
I hope I helped a little.
I never used the CD for lippincott because I thought the CD was too easy. I used the questions from the book and they are all different. I would photocopy each exam and take them. I would do one page, then check my answers, go to the next page, check my answers etc.etc... Then I could easily jot notes right next to the questions that I had trouble with. I kept a folder of all the exams I took. I have a photo copier at home so it was easy for me to do. I just didn't want to write in my book. If you want to write in your book, then don't make copies. When I did do the exams on lippincott CD's I would score high 80's. This is why I say they were easy because the books exams, I would score 50-60's and as I got closer to my exam, I got to high 60's to low 70's.
I liked lippincott bettter. I thought the rationales were more thorough and explained why each answer choice wasn't right or wrong. I know on Saunders sometimes it will say, Answer 1 was a better choice. etc. Lippincott doesn't do that. After taking the NCLEX exam, I thought lippincotts questions prepared me well, especially for those topics you don't see very often. I also thought they were similar to the NCLEX in that I could always narrow it down to 2 really good answer choices.
Good luck on studying!! Like Suzanne said, take a days break. I would sometimes if one day I stunk it up!
