Revision material for certification

Hi I am new to the forum. I am 32 years old and studying at University for a Bsc Hons in Computing at the University of Ulster Coleraine in Northern Ireland. I loved Java in first year and now that I'm on placement want to use the time to gain certification. I have go Daniel Liangs 6th edition Java Programming, Head First Java and the SCJP for Java 6 book. Is this enough to allow me to certify. Should I also be looking at other material? any advice is welcome. For any of you lucky enough to be employed as programmers / software developers is there anything else that could help me when going for a job i.e a friend told me to take a course in advanced or A level Maths?

I would think SCJP for Java 6 is the book to read. I did two Java courses at University and reading this book make me thinking I am new to Java. There is a large amount of details in this book. It is not made for beginners but for people who know some Java and want to prepare specifically for the certificate. Personally, I think writing lots and lots of code is very important, so when going through the book I write lots of small programs to try out what I have read. The book contains a CD with mock exams which are very useful. In the exam you are told how many answers you have two choose, but in the mock exams from the book you are not told. This makes the mock exam a good learning experience and much more difficult than the real exam. So most people do much better in the real exam than in the mock exams. I have also bought the Enthuware mock exams which I find very useful. Hope you enjoy the preparation.
