Hi,
I had only 5 days to prepare for the exam

(and 6 years
java coding experience ).I passed
SCJP 1.5 yesterday with 62%. Just scraped through. I did a thorough reading of the K&B book. Read it in and out about 3 times and tried out the examples in the book(4 days). I spent a day trying out mock tests.
Some tips: Working out the questions at the back of each chapter of the book prepared me more than half way for the
test.
Mock tests on the cd accompanying the book were great and close to the real exam.
Marcus Green exam was good too.
Just make sure you write enough mock tests before the actual exam.
I read posts at JavaRanch regarding the exam and peoples experiences.
When the exam began, I found the initial 8-10 questions to be time consuming so I marked questions that were taking time and did the simple ones first. Once I answered the simple ones and was reasonably confident and comfortable, I came back to "Big" ones.
If I tried to revisit a drag and drop question, I lost my previous answer. Did anyone face the same or I clicked some wrong button?
I wrote the exam at a promteric centre in Bombay. They had scheduled me for 10:00 in the morning but my turn came only at 12:30 at noon. There were several others waiting for their turn . Reconfirm your exam time maybe twice thrice so you dont have to wait before the exam.
The exam was not difficult. Time was sufficient.I guess I needed more preparation.

All the best to others taking the exam.
