Great news to hear...................
The 100 questions work out perfectly, as you should do at least 3000 to 4000 before taking the exam. If you do 100 daily, then you willo have 3000 done for the month, and another 1500 if you have six weeks. By the time that you actually do the 100, and review each and every rationale, your brain will be exhausted, and you will not retain any of the material. I have found the best results when you only do the 100 per day. It is extremely important to understand the trationale behind each and every answer.
Hope that this helps...............
