in your post you said "I am new to use hotpot. I am going to use this module so as to create quizes", but actually the HotPot module doesn't create the quizzes, it only allows you to administer them via Moodle.
To create a Hot Potatoes quiz, you need the Hot Potatoes programs. These programs run on your PC. Actually there are 6 programs, but they are usually referred to all together as just "Hot Potatoes". You can download
"Hot Potatoes" from the following URL
The Hot Potatoes website has some good tutorials on how to create quizzes:http://web.uvic.ca/hrd/halfbaked/tutorials6.htm
Once you have created a quiz on your PC, you upload
it to your Moodle site and add it to your course as a HotPot activity.
Please be sure to use your Hot Potatoes quizzes according to Hot Potatoes license:http://www.halfbakedsoftware.com/hot_pot_licence.php
all the best
