SCBCD preparation

Hi all,
I am Sun Certified Java Programmer and Interwoven Certified Consultant. now i want to go for SCBCD but the thing is i don't have any experience in EJB's an i have quite a good knowledge of JSP and Servlets and i even read Hanumant Deshmukh once or twice but din't appeared for SCWCD exam.
what do u people suggest ? should i go for SCWCD first or i should directly start preparing for SCBCD as i am very keen in learning EJB's and some Application Servers.
if i should start preparing for SCBCD where should i start from ? as i have very less knowledge of EJB's almost no knowledge.
also ho much time will it take me to go for SCBCD exam.
please do help me in deciding.
cheers,
Rahul Juneja
