Is this contest rated?
codechef never mentions this in their contests.Please make it a habit to write whether a contest is rated or not in future contests.
The contest is not rated. You should always assume the contests such as Cook-Off, Lunch Time and Long Challenge to be rated until there isn’t any exception (which is always intimidated to the users well in advance). Moreover, if there is any externally rated contest, it is mentioned along with it’s name. Also, Battle of the Chefs is not rated.
