I have read previous posts which highlight the value of completing all the questions in the question bank (I'm trying!), reading all of the the rationales and making notes. I just wanted to add that I find it useful to do a daily test of 'incorrect' questions, I answer them thinking through why the answer is correct (sometimes articulating the rationale out loud) and it boosts my confidence to get the majority of them right. I do this first thing to give me a good start to the day as it shows I am retaining the previous days learning :-)
At the end of the day I do a short test (25) of 'all' questions, this gives me a mix of new and old questions and again ends the day on a positive note as I tend to do better in these tests that all 'unused' questions. Hope this suggestion helps!
Would like to hear others' learning strategies...

Thanks for the suggestions I'm gonna try this.

I have been studying 45 unused questions M-F and Saturday test on incorrect questions 45-75. By Sat. I'm exhausted so its an "easy" day and then I take Sunday off to spend with my family. Although I was just thinking earlier today that maybe after I test and review the unused questions that I may add a little of the incorrect questions daily. But it would totally depend on my time and what my day is like. I have 3 kids and a husband, lol! I tried doing 75 per day and it was just too much. Testing 75 was ok, but reviewing the rationals was overwhelming me and called for a long day and still needing to prepare dinner, etc. I played with different amounts and found 45 to keep me sane. Praying this is enough for me to be able to pass, otherwise I don't know what else to do :/ With the 3 month purchase I got the total number of questions and divided into how many days I have with this program, not including weekends, and shortened it. I'll have all questions done a week and a half before expiration which gives me time to continue to review my "marked for later" and any more incorrect questions I have.
