Is CFA Level II exam difficult to prepare?

I am seeking the CFA Level II exam preparation resource because my final exam is near. I want to pass the test on the first attempt. Does anyone recommend the practice test?

I have passed my test. I took CFA Level II practice test from P2PExams and it was helpful. It helped me prepare successfully for my exam. I recommend every candidate must utilize this CFA Level II practice test material before taking the final exam. My overall experience with P2PExams was excellent.
