Congrats Rizwan
.
Judging by your cert status, i would try the Developers exam. This will give you some hands on experience and you will learn a range of new technologys (Swing, Threading, Socket/RMI. etc).
Or, you could go for the
SCEA exam. Although this has a practical exam also, this will mostly teach you how to design applications (along with learning some UML,
J2EE patterns, etc).
All the best.
