Please take a look at the following preparation tips for the exam. 1. Go through RHE and Mughal's book chapter by chapter till you finish the syllabus. Read one chapter from one book and then read the corresponding material from the other one too. Both the books are good but some things are better explained in one book as compared to the other. Do keep on trying out the examples and other code as you go along. 2. Then re-read one topic at a time (from these two books again) and start taking the topic exams by Dan Chisholm (or if you can get hold of any other topic exams). 3. Simultaneously with step 2 above, download Velmurugan's SCJP preparation notes and read them topic by topic (after taking Dan's exam for that topic). Now, you may make mistakes in Dan's exam or in the other topic tests you take and you may have important things to jot down of your own. Note down these additional comments in your copy of Velu's notes. His notes are very good otherwise and shall need very little tweaking. But there are a couple of mistakes that I found in the notes (or may be in the language used to explain a concept) so don't forget to test anything doubtful. 4. When you are through with these 3 steps, start taking full-mock exams. Take at least 7 to 10 of them or more if you have time. 5. Keep the Marcus tests and Valentin's test until the last 10 days. If you score 80% plus in the Marcus tests and around 70 in Val's then you are ready for the exam, but target a higher score. I followed these steps (not to perfection though), and got 85% today in SCJP 1.4. I had got 83 and 85 in the two Marcus tests I took and 79 in Val's test. I was targeting 90+ but I think must have made some silly mistakes in the exam for I did not find any of the questions really tough except two or three. In the exam, there is sufficient time but not enough to revise the entire exam thoroughly again. So try to concentrate and get every question right the first time around rather than banking on revising all of them. These are my personal views and you may tailor them suitably. ...and last but not the least, don't forget frequent visits to javaranch. Best of luck.
