Restricted Radio Telephone Operator Certificate
 

I need to write the Restricted Radio Telephone Operator Certificate exam within this week.

If anybody can provide me with any material , except the guide in the website, which will help me pass the exam will be highly appreciated.

Talk to your flight instructor, they can give you some reading to do. I would recommend reading the chapter on radio communication in "From the ground up". Read a few pages letter by letter using phonetics to learn the alphabet. Read the info found in the CFS, understanding who to talk to is just as valuable as how to communicate "properly".
