SCJP/OCP Java 6 Resources

The Oracle Certified Professional (OCP), Java Standard Edition (SE) 6 Programmer certification is an entry-level credential that validates your skills in the Java programming language.

I'm studying for the SCJP 310-065 which stands for Sun Certified Java Programmer, for Java 6.0.
But, as you know, the Sun was bought by Oracle and the exam code has changed. Now, the official Oracle exam code is 1Z0-851: Java Standard Edition 6 Programmer Certified Professional Exam

I'm reading the Kathy Sierra and Bert Bates book SCJP Sun Certified Programmer for Java 6 Exam 310-065, from McGraw Hill,  and until now everything is clear as crystal - unless for some details that I don't work with in my daily job as a Java Programmer. But I'm learning all these details! From this book I recommend the "Two Minute Drill", that comes in the end of each chapter, that has all the details that you need to know from each chapter.

I also have the book OCP Java SE 6 Programmer Practice Exams (Exam 310-065) (Certification Press), also from Kathy Sierra and Bert Bates, for practicing (these are really hard exams!):

But... who are these two guys?
Why should I read and prepare with their books?

Kathy Sierra is a co-developer of the SCJP exam and Sun's practice exam. She is also a Sun Certified Java Instructor and the founder of the world's largest Java certification website, Javaranch.com.
Bert Bates is a Sun Certified Programmer for Java and has participated in the development of the SCJP exam and Sun's practice exam. He is the coauthor, with Kathy Sierra, of the previous editions of this book.

So, now you can see why these two books are very important for studying for the certification.
