I've just replied to your post about the "old exam questions".
I guess the question in this thread and its answers would be more positive.
I would suggest the following:
1- Study your materials very well. Write your own notes, questions etc on the textbook so you can go back to them when you need. Ask questions during your course.
2- Use one calculator during your study and exam. Ensure you know and practice using the special functions like logerithic calculations (if they are included in your exam) and brackets.
3- Know what will be given to you as an aid in the exam. Will you be given a formula sheet, graph papers, ruler etc? Bring with you what you could possibly need (but allowed).
4- Ensure you understand the terms used in the materials. Some terms may have similar meaning but the exam writers have an objective of differentiate between the examinees. One way of do so is using similar terms.
5- You may need to memorize some equations or shortcuts.
6- Ask for an exam version for the units you are familiar with (imperial or metric).
7- Based on your involvement with real vibration analysis, you may need to review the materials of the lower categories.
