I also purchased WhizLabs for my preparation. My average score was 77% on WhizLabs and on the real exam I got 91%.
You simply have a Ferrari on your hands.
However, I totally agree with Edwin. If you don't careful read all the explanations and practice all the questions, you may fail the SCJP
As I said you have a ferrari but you have to learn how to drive it.
My atack plan when I purchased WhizLabs was as follows : (Read careful) 1.
I wrote the Diagnostics Exam. When I finished I walked through ALL questions including both the correct and incorrect ones, and careful read the explanation provided by WhizLabs.
Those questions I found interesting or tricky questions, I marked them for bookmark for later review. 2.
I wrote the Practice Exams #1, #2 and #3 always reviewing ALL questions after each one and marking for bookmark those questions I found interesting. 3.
Before start the Practice Exam #4, I started a customized exam containing ALL questions I put on bookmark. And here, again, I walked through ALL questions, correct ones and wrong ones, after finished the customized exam, careful reading the explanations provided by WhizLabs. 4.
. At this point, you can imagine how big is our incorrect questions database. Hum, so before start the Practice Exam #4, I started another customized exam containing ALL questions marked as incorrect from all the previous exams. After finish, again I walked through ALL correct and incorrect ones. 5.
I started the Practice Exam #4. Again, reviewing all questions after that. NEVER forget it ! 6.
Now I have finished all Practice exams and I would be tempted to go for the final exam. Don't make this mistake!!! Go to Quiz questions first taking all the 150 questions in only one sitting. When configuring such customized exam, 50 seconds for each question is really challengeable. 7.
After that, You're for sure prepared to the final exam. So go ahead and DON'T forget to review all questions from this exam as well. 8.
On day before the exam, if you have enough time, start a customized exam containing all questions marked as incorrect from all the previous exams. 9.
And FINALLY, DON'T FORGET to read the "Tips n Tricks" and the "Review Notes" provided by WhizLabs. It's a very good stuff.
At this point I think you are really prepared to score more than 90% on the real exam.
Sometimes, the start exam, review questions, start exam, review questions, and again, again, again ... can make your study journey simply boring !!! DON'T SURRENDER. THERE'S A PARADISE WAITING FOR YOU on your D-Day.
Good luck on your study journey.
