Book 1 - Ethical and Professional Standards and Quantitative Methods

Currently I'm attending in a preparing course. And there are exams. I did well, got 85% in Ethics and 100% in Quantitative methods. However I think the scores are somehow misleading, I still don't feel so confident in any of these 2 fields. The book is really useful, specially in the field of quantitative methods. If you're going to take the test and you have enough time, I recommend reading this book instead of guide books such as Schweser Note.
