CFA 3 Mock Exams

I read somewhere in the discussions about Konvexity and Bill’s mock exams. Any experience with these providers with recommendation for one of them. Also what is the website for Bill’s exam - where to buy them? Or any other recommendations for the mock exam provider. On top of questions, I am looking for the provider which provides efficient and effective way of writing a.m. essay exams answers
