One of the thing i did preparing for my SCJP exam was trying out as many sample questions available.
I also tried a exam simulator called ExamLab for SCJP 6.0

ExamLab for SCJP 6.0 is a free exam simulator that is designed for the Sun exam, "Sun Certified Java Programmer 6.0". This simulator contains one diagnostic exam, three practice exams and one final exam.

Real Exam Interface
The software interface of this product is very similar to the real Sun exam. You can be well experienced with it, before taking the real exam.

Objective-based questions
All of the questions in our product are fully oriented on the Sun exam objectives. Nothing is out of scope.

Detailed explanations
Detailed explanations are provided in the review mode.
Exam History
Your exam history will be saved automatically for further evaluation.

I can say one of the reason i passed my SCJP exam was with the help of the simulator. It was very helpful in getting the real exam feel as it's format is very similar to the real exam. The questions are even tougher than real exam questions, but the explanations was quite helpful in understanding various types of questions being asked in real exam.

Unlike many other exam simulators, this one is totally FREE. Feel free to browse the website to download the software.

P/S: i'll write about the book i study for m exam preparation in next entry.

Hmm... what is the purpose of "downgrading"?
May be...
1. more students can get 1st class and their ptptn can become scholarship?
2. to standardize with other universities?
3. syllabus are getting tougher?
4. etc...

what ever it is... its a good news for students. Hope they score better.
