Exam Certification

Next Tuesday I am going to take the Exam 834: “IBM Lotus Notes Domino 8 Application Development Foundation Skills” exam.

I wonder if someone could suggest me which is the best book/article to study.

also I would like if someone who took this exam want to share his/her experience.

Another question: Which is best ?

1.- Take de 3 exams of release 7 and then take the update exam for release 8, or

2.- Take directly de 3 exams of release 8

One more: I have read de “Lotus Notes 6 - A developer Handbook” which is very good but I did not find this kind of material for R7 or R8.

Some could help me ?

Thanks

PD: Sorry my english is not very good !!
