unable to tick all the check box under a single page selenium webdriver

[Mujib]

I am facing problem to apply loop and tick all the check box under a page.

Kindly suggest me to tick all the check box in page. Please follow the below steps
1. Go to Url "http://kesdee.com/buyOnline.html"
2. Go to dropdown'Course Groups' and select "Bank Branch Management"
3. tick all the check box under 'View Less' link
4. click all the 'View More' links one by one and tick all the check box
