Thanks everyone.

I think I'll forget about the SCJP 5.0 upgrade exam and concentrate on the SCJD!
Please excuse me for my ignorance. What is the SCJA exam, and is it more suitable for students and project managers rather than actual Java programmers/developers?

I already have a SCJP 1.4 and is now working on a SCJD. Should I also attempt with the SCJA?

Lastly, is there any good books or study aids on SCJA?

I already have a SCJP 1.4 and is currently working on a SCJD. Should I also try to upgrade my SCJP to version 5.0? How diffcult is the upgrade exam comparing with the full exam?
Thanks, Mr Monkhouse. Unfortunately your link leads to, and I live in the UK. The price (including international shipping) is around the same as (with free shipping for me), but there is a big difference in the delivery times. (9-36 business days instead of 3-5 business days.)

I'm definitely going to buy this book, most likely from Please let me know if there is a similar link for

I don't want to wait too long for a good book!
Mr Monkhouse, after reading your description of your yet to be published book, I think it will be a very good book on the SCJD. Can you tell us when will your book be published? (An approximate date will do.)
I know that Sun's policy on SCJD submission is that the assignment must be developed under a production version that has not been superseded by a new production version for more than 18 months. Does this means that, if I'm using Java 1.4 to develop my SCJD assignment, I must submit my assignment within the next 18 months? Does anyone has the exact deadline on when I must submit my Java 1.4 submission for SCJD?
Thank you everyone for answering my queries. I've decided to register for my SCJD assignment in late October, since I have a major deadline in early October.

Oops. Forgot to ask this.

I only have access to a PC. Will this be a problem because Java is a multi-platform language? Will the examiner test my assignment on other platforms such as Linux?
Hello everyone:

I have just acquired my SCJP 1.4 about 8 months ago, and I'm planning to do the SCJD now. However, I have many queries that I want to clarify before attempting it.

1. With the release of Java 5.0, does this means I must complete the assignment using JDK 5.0 instead of JDK 1.4.2? And will the assignment be tested on JRE 1.4.2 or JRE 5.0 (or both versions) by the examiner?

2. I'm hoping to achieve this in around 12 months, although I can allow myself up to 2 years to complete it. I should be able to allocate between 8 to 10 hours per week. Does this sounds reasonable? (Sun's web site actually said that it takes only one working week!)

3. Should I buy Kathy Sierra's Java book? I have already bought Mehran Habibi and Philip Heller books. My weakest area on the SCJP was the Threads, and since my SCJP is version 1.4, I have little experience on the GUI and File IO, and no experience on Network Server or anything Database-related. Any recommendations on books that could help me?

4. If I fail this on my first time, do I need to create another new assignment completely, or is it sufficient if I corrected the mistakes and re-submit my original assignment (with modifications)?

5. How likely is it to pass the exam on first attempt? If someone fails on the first attempt, is it likely for him or her to pass on second attempt, or does this implies the person will likely to fail again?

Thanks in advance.
