. I followed OCA/OCP 7 book by K&B and when I was done with my preparation I finally bought mock exams from enthuware. I must say the quality of exam in enthuware is really good & the kind of explanations you provide is just awesome and now that I passed, a lot of credit goes to you guys. Your forum's been very useful too. You guys rock..Keep up the good work.Now I'm planning to take OCPJP 7 and will buy mock this time too.
