Thanks Adrian, Badal, Doug, Mapraputa, Hema, Vani. Thanks to all the javaranchers for their suggestions and comments.
Badal, Sorry for the delay in the reply. Here are the answers to the questions you asked :
1. I found this test 141 tough and could score just little more than the passing score( 66%).
2. My score in SCJP was 78%.
3. Before preparation, I would rate myself 3 out of 10 and now I believe, I am somewhere near 8 out of 10.
4. Yes, I did go through articles from "Roger L. Costello" on XML Schema but not XSLT. For XSLT, I referred XSLT/XPATH Tutorial at www.zvon.org
Thanks and Good Luck!
