Hi Prashant,
I think, the preparation for 310-220 and 310-230 is slight bit different and sun is going to invalidate the earlier version in next couple of weeks. I took the older one because i started preparing long time back, so my preparation might not match your requirement. Anyways, I prepared these stuffs:
RMH(if you are a newbie, this should be your starting point)XYZ materials and mock exams (this materials are crisp and stright to the point)MZ Notes and MZ quiz(It's recommended to refer his notes for last couple of objectives, though the entire note is pretty good)Ivan's note (This is for mainly SCDJWS 1.5 though i covered some topics from here too)
Thanks and best of luck
