Great time to be asking! I'm going to sound like a broken record to those who frequent this forum because I've given my opinion on the topic many times. But here it goes again!
You have all the right materials-- here was my surefire way of passing (and actually doing extremely well) on the peds boards- keep in mind this is from someone who did below average on all the ITE's the three years prior because I hadn't prepared for those. The peds boards are the perfect example of a test that can be rocked with high yield studying. What I did- and based on the materials you have obtained, this will probably work just as well for you if your study style is more self-directed.
1. Took three-four months outlining Laughing Your Way-- I did this in a notebook but if flashcards are better for you, that's fine. That notebook became my bible. Every night I read my notebook for a few minutes. By the end of those months and the exam I had the contents of my notebook memorized and completely internalized
2. In the last two months, read through First Aid to identify any gaps from LYW. Outlined those. There weren't many, but some topics were better organized in First Aid.
3. Did all the PREP throughout I could get my hands on. More years the better.
4. Looked through Zitelli a bunch of times to get common pictures cemented
On test day I was surprised by how the test seemed based on my high yield studying. Sure there were some questions that seemed impossible no matter what I had done. But it was a study plan that produced results.
Good luck.
