i passed on SCBCD exam just study by Manning Book and Enthuware simulate, and i think that was suficient, no more, no less.
you can find Manning Book on PDF ( eMule ) or buy on amazon, and Enthuware simulates you can find in Enthuware web site.
time is very close to your experience, i think that if you spend 2 hours by day (follow manninb book index), in 2 months ( study and
test ) you are ok to take certification exam.
