2 more correct questions and u would have passed. May be next time you get prepared to get in 90s. Well, atleast you won the voucher from Javaranch. There are people who have paid and didn't get thru. This is how u need to convince yourself and get very goooooood score next time.
And concentrate on the areas where u didn't get thru as EJB, Internationalisation, Security, Legacy connectivity. Re-read oreilly (ejb), java tut(i18n), ibm Java 2 network security (security) and jamie and John's notes and legacy connectivity.
Please post any queries / doubts. Next time u will surely succeed.
