Passed
SCJP 6 today with 88%. K&B for SCJP 6 along with a few mock exams over a period of a month (3-4 hrs a day) should take you through.
210 minutes is more than ample time if you're comfortable with the concepts. Actually it took me just over an hour to complete the exam. (On second thought -should've devoted more time to revise my answers, could've scored more !!!)
