I passed SCBCD (310-091) exam yesterday. The exam is really tricky but with the right preparation you will pass.
I made a mistake of purchasing a voucher early and never got time to read because of work pressure then in the last 2 months I had to do a lot of reading so as to write before the voucher expired. I used O'Reilly's book, tried a lot of examples and used Glassfish App server. I urge those who want to write to practice a lot because you understand the concepts better. I also relied on the SPEC (boring to read but MUST read). I found the exam quite challenging but the time allocation is good. There is plenty of time so you are not under pressure when you sit for the exam.
Also I think the key thing is NOT only to pass the exam but to understand the concepts and be able to apply them given a problem in a work situation.
Thanks to all the ranchers and those who post their studying experience. It gave me confidence that I can DO IT.
