Sorry to hear about your experience.
I had Yeager and really appreciate the fact that I could talk to him about questions I was having problems with. Here’s what I did for Reg. By the way, I passed it on the 2nd try.
1. Watched the lecture
2. Did the assigned homework
3. Did 30 questions on Wiley TB.
4. If I did not understand a concept I did not move forward till I understood it. (REG was my 1st exam so I had all the time to waste with it. In addition, I was determined that another failure was not an option.)
5. As I progressed in my studying (moved from one chapter to chapter to another), I made sure I did some form of review of the chapters that I have completed. E.g. if Module 3 is the new module, I will do 30 questions from Module 1&2 before starting to study module 3. As I progressed to module 4, I will do 30 questions of module 1, 2, &3 before starting module 4. This kept the materials fresh.
6. Saturday mornings I will read all notes that I have written.
7. When I was done readying the materials, I started working on timing. I practiced 80 MCQ and 7 SIMS and tracked the time it took me to complete it.
8. I also spent time on the questions I was always getting wrong. I read the material and if I still did not understand it I called Yeager.
9. It was painful. Took lots of hours. I had my moments….crying and feeling sorry for myself but another failure was not an option so I prayed….A LOT and threw myself at the material.
The most important advice is what you do while taking the exam.
1. Try your very best not to be discouraged while taking the exam.
2. Remember to do “memory dump”
3. If a question looks Intimidating, flag and work on the others. Return to it after you have solved the other questions in the testlet.
4. Before the exam make sure you allocate time for each testlet. During the exam keep to that allocation.
5. For the simulation, I always scan through all the SIMS. I solve the easiest 1st and leave enough time for the difficult ones.
6. For the difficult one, I did not guess. Based on what I know about the topic, I create my formula and solve it the best way I can.
Wish you all the best! Make sure you know the material. Don’t rush yourself. Some people study for a month and pass, some study for months. We are all different. Do what works best for you. Whatever gets you to understanding the material.
