Hi Shalu/Chao-long:
As one of our Java educator pointed out, 1.4 has lower passing score 52% than 1.2 (61%), fewer questions, but by no means easier than 1.2. For most people, it's much harder for the reason to lower the passing score. Again, all depends on what direction you are heading towards,
SCJD or SCWCD both require SCJP2 (no matter 1.2 or 1.4). Lots of people have prepared for 1.2 and have passed 1.4. If you have the level of depth, AND familiarize yourself with new objectives (make sure you do understand thoroughly) for 1.4, you can choose to take 1.4. But again, it's harder than 1.2 for most people (especially when you are not coding heavily).
Hope it helps,
