Hi Sumit,
Barry Gaunt also has highlighted a very important issue.
Some people have reported that when reviewing their answers for drag 'n' drop questions, they realized that the question had been reseted.
So, it's recommended that after go away from a drag 'n' drop question you put your answer in a piece of paper just to avoid the situation where you have to re-evaluate entire question and waste your time if it's reseted.
I am also planning to write the exam in the end of March. Maybe between 25th and 30rd.
I've been studying for SCJP since Jan 18th. I am using only K&B Study Guide for SCJP5 which is a very good book. It's enough.
I'm almost finishing to read entire book. Maybe this weekend.
After finish read the book, I will concentrate my efforts to practice as much as questions I can. I've heard that those guys who got more than 90% have writed and praticed a lot of code and questions.
If you are able to spend some money, I highly recommend you to buy WhizLabs exam simulator (it costs US$ 59.95). It has over 582 questions composed by 6 full exams with complete reports plus 150 Quiz questions. Very good stuff.
Furthermore, Whizlabs is comprissed to refund you all amount you spent if you don't pass the exam.
Also there are a few free mock exams available on the net. You can see all links to them in
Java Ranch's FAQ.
I also recommend you to spend at least 15 minutes a day taking a look at posts in this forum. Here there are many guys who post tougher questions and tips. I personally have learnt a lot after join Java Ranch.
I hope it helps.
Good luck and welcome to Java Ranch !
