Blackbelt evolves

as time went by, javablackbelt evolved from what can safely be called an "ambitioned under construction website" to something working. there is an impressive number of exam-takers and registered users down there and the new moderation process seems to make life easier. belt-exams for yellow belt, as well as a few 'belt-relevant' questionaires are up and usable. few of the questions are indeed challenging, but most of them (only basic exams are ready to take) can be considered a cakewalk. noteworthy about this website is, that it does not limit its scope to what sun provides certifications for: there are spring, hibernate struts and jboss exams planned.
best thing though is that some mocks for sun exams and study-guides are to be found there.

if you did not yet, you should consider to take a look.
