I have cleared SCWCD with 94%. It was bit easy for me as I have experience on servlets and jsp for the past one year. Source of preparation: Since last month following this forum.Came to know many things regarding notes,mocks etc... Thanks for all of you. I have read HFSJ book once.Very nice book.Thanks for the authors. Read almost all the notes available here.Especially Mikalai Zaikin notes are very useful. Purchased whizlabs exam simulator(very useful) and gave all available free mocks j2eecertificate, enthuware etc.. Gone through the specs(Jsp and Servlets).
