examination confusion

Hello all,

Im on the coarse of learning basics in java. Im still a beginner. I have actually done my degree in Electronics. But somehow fell in love with Java:o:.

So, all im asking you people to give me a proper guidelines about the exams(SCJP,OCJP... or whatever) which im supposed to take up after my preparation!!!:)-:

please suggest me the exams rated from the most easier ones to the most difficult ones(step by step). I want to climb this java mountain from the ground to the top rather than trying to jump at a time(I guess you people understood what i said!!!).:(wait):
