As of now. Oracle fiddles with this regularly.

Both exams are largely code snippet analysis. Some of the topics on the OCP 7 are longer code snippets. For example, the code to walk a file directory or listen for changes on the file system can get fairly long.

I think it is. But that's because of the material. I did about the same on both exams though.

No. Our book tried to be harder than the exam to make sure you understand the correct answers and also so that you can recognize them quickly. There's a good change Oracle will change the number of questions on the OCP 8 over time.
In fact, Oracle lowered the number of questions on the OCP 7 last year. I suspect they did it because they wanted more people to pass the exam. Sometimes Oracle changes the number of questions on an exam by a very small number. This can't be to accommodate "types" of questions.
