Hey Dishaan,
Every thing you want about IBM-"IBM Certified Associate Developer" ( 285 ) should be here:
http://www-03.ibm.com/certify/tests/obj285.shtml The one book which is recommended by IBM is:
An Introduction to Web Application Development with IBM WebSphere Studio
Author: Gary Craig, Peter Jakab
This is a book by IBM Press and is highly recommended for this
Test.
For discussion on IBM 285 you might have to go to "Product and Other Certifications "
thread.
BTW, i am also having the same plan:
Doing SCWCD frist and then give IBM WEBSPHERE but not sure if 285 , 286 or 287 to give.
Some time back i did post my queries on this forum, you might want to read and suggest some thing to me:
Topic "SCWCD and IBM 285 "
Thanks and All the best.
