Passed the SCJP - 85%

I missed 9 questions out of 60.

80% Declarations, Initialization, and Scoping
90% Flow Control
85% API Contents
100% Concurrency
70% OO Concepts
87% Collections/Generics
88% Fundamentals

I used the SCJP book by Katherine Sierra and Bert Bates, the Rules Roundup here at JavaRanch, and my own notes compiled while studying for the exam. I worked every example in the book, created a custom sort module which will be useful on the job, created many small test programs, and performed many Google searches, as well. I'm just happy to have passed; I would even have been happy with the minimum passing score of 58%, because I REALLY didn't want to waste the 300 dollar testing fee, which came out of my own pocket. I feel the thing that helped the most, was actually compiling my own notes! There's nothing like writing something down, or explaining something to another person, for really understanding study material.

I studied for about 192 hours over a 6 week period, to ensure I didn't waste that $300. It may have been overkill, but not by much - some of the subtler aspects I discovered during that 6 weeks period, were on the exam, and had I not studied that long, I would have missed them.

A better score would have been nice, but I'm not going to beat myself up over it. I have some concerns about the quality control on the test. One of the questions asked 'Which 2 of these OO concepts are being illustrated?', yet gave me a radio button to pick two items! There's no way I could have answered that question correctly - I would have needed checkboxes to pick two answers, not radio buttons. Another question had as its function signature something like 'public int() SlapHappyCoding { // do something here; }', yet 'Do not compile' was not one of the available options. People who got 100% must not have gotten the questions I got.

I would say the questions on the test were equivalent to the easy-to-medium questions on the mock exams. The questions all seemed fair, and reasonable - I didn't encounter any questions like the ones I disliked from the mock exams, where you have to figure out this big long program, and calculate the correct answer, but STILL get it wrong because "you didn't import* up top! Har! Har!".

I don't know how much help the mock exams really were, in the big picture; after going through this process, I don't think they helped as much as I imagined they would. The first time I took them, I scored in the 50% area. I didn't feel too badly, because the tests contained new information that wasn't presented in the book, and several of the questions seemed unfair. The second time I took the mock exams, I got 95%, but at that point, how much of the score is due to knowing the material, and how much of it is recognizing the answers from the first time I took the test? It's like the mock exams are useful only once, but beware - they may come at the cost of gutting your self confidence. The main useful thing the mocks exams gave me, was this: be very, very careful in reading the wording on the question - sometimes they're not testing you on what you think they're testing you on.

Big congratulations, Cindy. After you posted a note yesterday morning that you were taking the exam in two hours, I (as everyone else) grew concerned from not hearing back from you all day. Well, as it turns out it's happy news and a nice long debriefing report from you. Many thanks.

Congratulations!!! Cindy!!!
Even i was waiting to hear from you, after your "taking the test after 2 hours"
Iam giving the exam on coming Wednesday. I was concerned my mock scores are not great. Now i feel little better.
Did you read the "2 minute drill" at the end of each chapter in K&B book, before the exam as recommended?

Great Job Cindy, congrats!

It sucks that your employer won't pick up the cost of the exam for you.

Your notes are quite thorough. Thanks for making these available!

I took the SCJP 1.4 back in Nov 08 and got a 49%...just short of the required 52% but only took 3 weeks to study (it clearly wasn't enough!). I am now studying again for 1.6 and agree with you about the mock exams...they sometimes seem overly difficult and I question how helpful they are.

Which mock exams did you take? Sun's Own or some other brand?

Thanks everyone!

I read the "2 minute drill" at the end of each chapter in the book, but I was disappointed by how sparse they were - they didn't cover lots of stuff that was presented in the chapter, that I felt needed highlighting. I don't think reviewing those 2 minute drills would be enough to pass the test - that's why I made my own notes. I wanted to present all the information that I was apt to get wrong, in a condensed format for cramming the day before.

The mock exams I took were the ones that came with the book. I also took Sun's mock exam, but it was very small, and didn't explain wrong answers, so I didn't count it when listing what I studied.

Basically, the notes should be considered as supplementary material for someone who's learning Java from other sources, such as the Sierra/Bates book. Though the notes are short, they ARE useful! I think the multithreading example I presented in Section 9 is quite compelling - it really nails home multithreading for the confused and befuddled. I also incorporated educational information in the notes that I DIDN'T find on the book or the mock exam with the book, such as the fact that you can't compare enums with < or > .

Feel free to use the ideas presented in the notes however you want. I haven't really seen a good treatment of multithreading in a Java book before, which is why I spent all that effort on Section 9; I think it would be keen if my multithreaded explanation makes things easier for future Java students.
I agree. Here's the link:
