Hi Kaly,
For reading, read the question first, and then go to its specific paragraph and look for the answer. If you still are not able to find the answer, then try to guess the best one.
For listening, do not write on the paper everything you will hear, just the main idea, details, and concentrate to guess by yourself the questioned questions, of course if you can...
Try to relax as much as you can during the exam, I know it's hard, but do the best.
Good luck and be strong.
