I just noticed that I passed PPP I took last week.
Let's go into the topic directly.
I use Architect Prep. study material which I think is the best and recommend to you guys. Then I use Jenny notes and Carline Notes.
My suggestion is that do not spend too much time on history, focus on renovation disciplines from the interior dept. if you have enough time, read CDS material and review the knowledge about AIA contact.
The last suggestion, every time finish Ballast and Kaplan mock exam, go ahead to google the topics you don't familiar, remember, wiki is a good teacher.
