Everyone is different, but here are a couple of quick comments:
- Are you seriously going to study 15 hours per day? Frankly, I worry that such a schedule will be counter-productive. Even a full 8 hour day of study would be difficult, but it seems far more realistic to me.
- Similarly, I would caution about a full 4 hour test every day. I did one every other day, with the day in between devoted to re-studying the areas where my last test showed I was weak.
Make sure to build in time to get some exercise, talk with friends/family and generally blow off steam. Get some fresh air, take a walk.
Again, you may well be very different from me (for your sake, I hope you are
), but for me your schedule would have been a self-fulfilling prophesy of failure -- I would have felt the pressure to pass, compounded by being exhausted by the study schedule -- and, in the end I would have tanked. I also had to finish my studies on an accelerated schedule because I had a sudden personal commitment come up, forcing me to finish in 1.5 weeks when I thought I had a couple of months left. In the end, I only did 4 of the practice exams before sitting for the real thing. It worked out, and while I worked hard every day studying (after work each day and longer on the weekends), I made sure to keep a more sustainable pace. I didn't want to walk in to Prometric's office physically and emotionally destroyed.
Beyond that, I think your general approach is logical, and I gained a GREAT DEAL of benefit studying my wrong answers after each full 4 hour practice test. I not only found the study areas where I was weaker, I also discovered habits I had while taking the test that were counterproductive.
All that being said, good luck!!
