The main reason I'm interested in the MS credential is to teach middle school core. I already have the book by Zarillo and I've used Teacherstestprep which has helped me in the past.
What book are you using to study? A professor at my school wrote this: http://www.amazon.com/Ready-Revised-RICA-Preparation-Californias/dp/0137008686
I found it really helpful. Our reading classes were structured around it and I passed the RICA no problem.
STUDY THIS BOOK: http://www.amazon.com/Ready-Revised-RICA-Preparation-Californias/dp/0137008686
Zarrillo.
SERIOUSLY.
Don't mess with quizlet- I found most of the questions/answers to be inaccurate.
Focus on case study examples.
