A nerve-racking situation tends to be one that is ''intense'' or ''stressful''. Some might describe the feeling before or during an exam as nerve-racking. Others could describe a particularly difficult job interview, or even a police interrogation as nerve-racking! 

Some teachers can find classes nerve-racking. I know that I have felt very nervous before meeting a new class for the first time, especially if the group is large. However, those nerves disappear once you get to know the students, and gain their trust. As I teach one-to-one classes, I don't get too nervous anymore. Even so, we must find out if our partner is suitable or not! 

Hello Hossein, here are a few examples :)

"Waiting for my exam results was nerve racking!"

"My boyfriend is a professional rally driver, being in the car with him is nerve racking."

"Can you call me when you land safely? It's nerve racking worrying about your safety."

It is a good word to express extreme nervousness or anxiety. Personally, it's nerve racking for me when I'm waiting for news that affects my life, or when I'm worrying about friends. I also find visa interviews or job interviews to be nerve racking. Even my driving test was nerve racking, and I also find medical tests to be nerve racking when I'm waiting for the results.

Just a quick correction, you typed "nerve rakcing" instead of "nerve racking" in your first sentence. I hope my examples help :)

Hossein, 

Regarding my personal ''nerve-racking'' experiences, I have a few!

I suppose one of the most intense was during a 12 hour bus journey in Northern India. For almost the entire journey, myself and the other passengers were on the road on the edge of a mountain; the wheels touching the edge. At one point, the bus was too full. I felt the bus stop, then move with all the weight of the passengers. I noticed the gasps from the Indian passengers who previously hadn't shown fear at all. It was at this point I knew I could do nothing but rely on the gods. With luck and faith, the bus started driving again and we spent a further hour twisting and turning through the hills and across the rivers. 

Hope this helps answer your question :)

really appreciate Max, but is there any personal experieence of that?
