When I was studying HFEJB, I made my own notes, in my own words. I found that writing notes down in my own words helps me to remember. coffee cram exams and sharpen pencil questions helps a lot, so don't skip them. If you need a break for a change, try questions in www.ejbcertificate.com
Here is how I prepared for the exam.
1. First read a chapter in HFEJB, and took notes in my own words.
2. Did all the sharpen pencil questions, and coffee cram exam for that chapter.
3. Then went to ejbcertificate.com and did questions of that particular chapter.
4. Then carried on to the next chapter, and repeated steps 1-3.
I hope this will help.
